Thanks for the run-down, GetOutofBox. =)
The reason some say Alcohol makes you tolerant towards Methylphenidate, is because apparently there's some evidence to suggest it combines with alcohol in the body to form Ethylphenidate, and then your brain gets used to the fact that the high must come from Ethylphenidate instead of Methylphenidate. Ethylphenidate appears to induce more euphoria, and have more of a crashing effect when it runs out of your body.
Interesting, this is the first time hearing about this specific stimulant. I think it's unclear whether the methyl group can be cleaved from methylphenidate and replaced with an ethyl donor in the body though. Chemical reactions such as that often require more than two compounds being in each others presence, or being metabolized together. It's certainly possible though. However, it seems ethylphenidate has a lower binding affinity to dopamine transporters and effects dopamine uptake to a lower degree than d-methylphenidate, and much lower than dl-methylphenidate. I think the issue is that it's effects are more variable, and hence can make users use larger doses to compensate, sometime resulting in excessive dopaminergic activity.
I would note that alcohol could reduce the rate of addiction to a substance, as it is a moderately potent NMDA antagonist, drugs of which reduce downregulation. However, it may compensate for that effect by potentiating stimulants, as ethanol also produces fairly large releases of dopamine in various areas in the brain.
I should probably note that I myself is actually more or less a straight-edge type of guy, I usually don't drink at all, even at big celebrations, and I'm very picky with the nutrient-values in my food. I eat a lot of raspberries and almonds for the magnesium, for instance.
So, I was mostly asking for my friends, who have this problem that needs solving, and I'm the type of guy that jumps at problems and want to solve them immediately.
Yeah, there's nothing wrong with some drinks, it's when the brain is regularly being exposed to large amounts of ethanol you start seeing problems.
I must say tho', this ketamine doesn't seem like a very nice drug, the reported k-hole-effect seems positively scary, even! o.o
Yeah, it's very different than alcohol. But it's pretty much the one similar recreational substance that also is less unhealthy in the long term. Taken in small doses it produces effects similar to alcohol intoxication, but also very different in some respects. It has the benefit of being much simpler in it's actions, whereas ethanol has several MoAs, all of which are potentially negative in the long term.
Btw, interesting idea about Agmatine - do you figure it could actually work better than a nootropic stack? I'm especially interested in the problem with the calcium-levels - some Bipolar, and other type of disorder-suffererers, such as ourselves, report improved symptoms on mega-doses of Magnesium, I believe.
I would add it into a stack. It's pretty benign in that it's not very psychoactive on it's own, so it's unlikely to produce negative side-effects. The anti-calcium channel effect is moderate, so it may help shift things back to normal for those with erratic activity, but shouldn't negatively effect those with normal activity. Interestingly, it also potentiates several substances, especially cannabis. It's been found to potentiate cannabis' activity at CB1 receptors.
Magnesium is always good to add to a stack (I wouldn't "mega-dose" though, simply taking enough to fulfill the RDA should be sufficient for most people. Mega dosing can produce some positive effects in specific cases, but has the tendency to produce diarrhea),
as a large portion of people eating modern western diets are slightly to moderately deficient (along with several other nutrients too). The body is fairly good at handling minor deficiencies of most nutrients (especially the fat soluble B-vitamin group), but mineral deficiencies are more difficult to compensate for as they are not stored in signifigant levels in the body. Your body gets most of the magnesium/potassium/sodium/calcium it uses from daily food intake. The minor magnesium deficiency many American's (and you can probably extrapolate that to those with similar diets, such as Canadians) suffer from is unlikely to be clinical for most, but could produce neuromuscular signs such as cramps, and neurological signs such as minor bouts of unexplained anxiety, irritability, depression, fatigue etc. Not everyone manifests symptoms of sub-clinical deficiencies, but many do.
Like, for instance, IMHO, this stack is what I always presumed would be ideal for Bipolar:
1400 mg Omega-3 oil
4x pill of Magnesium-Citrate
15 mg ( two tabs, I believe) Lithium-Orotate
DLPA ( to help with potential brain-fog, unsure of the dosing)
I would make that 2 grams of Fish oil (specifically Fish oil, as non fish sources tend to have very poor bioavailabilty, as they contain ALA, which must be converted to DHA and EPA. The conversion process is very inefficient). Make sure the fish oil is microfiltered, as it can contain mercury levels which can accumulate over long term usage.
I don't know how much 4x pills of Magnesium Citrate is, so I'd advise 400 mg. If the person has a relatively good diet that should be enough. If diarrhea is encountered, split it into two 200 mg doses.
The lithium is tricky. That is a fairly low dose which is good, but I would still get a thyroid/liver/kidney workup every 6 months for the first year of using it to be safe, as at clinical doses lithium fairly often (1-10%) causes hypothyroidism, and can cause renal/hepatic issues (to a less common degree, but still possible). Ordinarily doctors will do said workups when prescribing lithium due to those side-effects. Also, although lithium orotate looks very interesting, there is a very large lack of human studies, so little is known about it's pharmokinetics in humans. The studies indicating the elemental lithium availability from it were done in rats only. I would probably microdose lithium carbonate instead, as you can be more sure that you're actually microdosing it due to it being much better researched.
The DLPA may help for a bit, but I suspect that just like L-Tyrosine supplementation, the rate limited enzymes involved in metabolizing it will eventually adjust to elevated levels, resulting in lower uptake in the brain.
A study in those with ADHD found positive effects on mood that were abolished in all participants by 3 months of usage (note that doesn't mean the effects will last 3 months, it means that by 3 months all participants stopped experiencing positive effects. The specific data isn't available, but I suspect the majority of participants experienced effects for only 1-2 months, that's usually the time required for complete upregulation/downregulation to occur). If the resulting depression is severe, I would probably add a low dose of an SSRI on to the stack, but SSRIs can be voletile in those with bipolar (not as risky as tricylic antidepressants, but can still induce mania occasionally).
BUT, in theory... if Bipolar has to do with Calcium-channels, then perhaps Mega-doses of Magnesium and a bit of Li-O is all that's needed? I do believe one of the reason why us westerners have so much more depression than other cultures is suspected to be because of Magnesium-deficient food, and a highly Calcium-rich dairy-based diet, yes?
So, using the superior bio-availability of Li-O in small doses, one gets a more stable mood, and with mega-doses of Magnesium-Citrate, one takes care of excess calcium! =) Done! Square! Sealed!
The problem is not that those with bipolar have too much calcium in their bodies, it's that calcium channels in neurons are remaining open longer than they should. Mineral channels (potassium channels, sodium channels, magnesium channels, etc) are part of how neurons neurochemically signal each other, different levels of electrolytes alter the voltage potentials of the neurons. Reducing global calcium levels in the body will do more harm than good, as calcium is very important to several biological processes. The goal is to simply inhibit excess calcium channel activity. Lithium seems to have calcium-channel inhibiting properties, but it also has a lot of other MoAs which have the potential to produce greater side-effects. More selective agents are currently being investigated, but it'll be a while before they enter mainstream use.
If this actually works... then in effect curing Bipolar-disease with such a simple noot-stack of supplements, is almost bafflingly simple, in comparison to curing ADD, now innit? 0_o
Unfortunately, it's probably not as simple as that. The neurological deficits involved in bipolar are still not entirely clear; the calcium-channel hypothesis is just one facet of possible dysfunctions involved. Also, it's not as simple as just inhibiting excessive activity, or increasing deficient activity, as doing so will inevitably interrupt other neurological functions, producing side-effects. The attainable end result right now is not a cure, but a band-aid. You can squash the mood fluctuations, but often at the cost of general emotive experience in general. Flat affect (blunted emotions) is a common side-effect of mood stabilisers at therapeutic levels. Cognitive effects are also common, such as memory impairment.
Now, nootropics have the potential to have positive augmentive effects (perhaps reducing memory impairment, etc), so I'm not saying they're useless. But don't expect a total cure.
