Pursuant to my comments above, I have a few feedback points to make regarding INI, which I started a few days ago:
1. If INI increases postprandial thermogenesis, then shouldn't we dose before eating, instead of after, so as to shut down the appetite ASAP?
2. Personally I find it easier and safer to transfer the insulin via a sterile single-use syringe (over several full loads), but to each his own. (I do have to use an alcohol swab to sterilize the rubber cap on the insulin vial first, which can be a problem because it can cause alcohol to pool there for a while, in the path of the needle.)
3. Pump the spray bottle sharply. Otherwise you risk allowing the insulin to dribble out, which will deliver excessive concentrations to all the wrong places, such as your throat. I suggest practicing once after you fill the bottle, if for no other reason than to ensure that the insulin has been siphoned into the pump.
4. If you're looking for a caffeine sort of zap, you'll be sorely disappointed. The effects build over days, if not months.
5. Speaking as someone with fasting glucose comfortably in the 70s, I must admit that I was surprised by the effects. Logically, it shouldn't work because I don't seem to have anything close to T2D. But perhaps I'm actually closer to T3D, thanks to the BBB separating regions of insulin resistance, thereby allowing the brain to become more resistant than the body.
6. As far as effects are concerned, it's thus far been sort of a creeping thing. At first, I seemed to notice that my memory for food flavors and musical tunes had improved, which is about the last thing I actually need. But today, I started noticing that my memory for essential trivial information had markedly improved as well, for instance, exactly where I had parked, which pocket I stuck my receipt into, etc. I also seem to be having less trouble retaining and recalling names of new acquaintances. I've also been running lots of errands of late to unfamiliar places, and have noticed that I don't seem to forget the way into and out of the buildings and parking lots. All in all, it's kinda spooky, considering that this is way too soon and my dose is way too low (2x10 IU/d) to foster any significant neurogenesis. I guess the neurons are being induced to slurp up more glucose and start cleaning out their waste products.
7. I got some ketone test strips lately, so I've been trying to find any association between ketone level, INI, and brain fog. The only thing I've been able to discern thus far is that when my ketones drop, I seem to get somewhat dumber and substantially less energetic. It's not at the "coconut oil miracle" level, but it's noticeable.
8. Emotionally, I've noticed nothing. I'm still a basically happy person.
9. I've been waking up with a sort of sick feeling in the upper esophagus. This is probably exacerbated by the giant blobs of fat I'm eating, but I'm pretty sure it's related to the "medicinal" odor of the INI that collects at the back of my throat. I guess we're stuck with this at least until a replacement can be found for metacreosol.
10. I'm not taking betaNGF at the moment; I just decided to try INI first, with galantamine. (I've actually only taken a couple 4 mg doses of the latter thus far, so it's not much of a factor at this point.) My general impression is that betaNGF is fantastic for visualization enhancement, whereas INI is more valuable for situational "street" memory that ones needs for daily activities. That said, I've experienced a few astoundingly detailed visualizations, but for whatever reason they haven't persisted for more than a few minutes, thus far. So perhaps I have brain energy deficits to deal with first.
11. Last but not least, the day after I started dosing, I had perhaps my worst ever episode of sleep paralysis (not to be confused with sleep apnea). As unnerving as it was to be stuck there, unable to move a muscle for minutes, I realized that it might have been confirmation that my neurological environment had been recalibrated in some significant way, causing me to succumb to a rapid repayment of subclinical sleep deficit. I can't think of any other reasonable explanation, considering the rarity of such events.
