Yeah, I was going to say that people's opinions of Mirtazapine seems to be that it is pretty emotionally dulling. There are a few receptor mechanisms that I think could be responsible.
I don't really know enough about Guanfacine, other than it's good for ADD in some individuals.
I have read before about people who get closed eye visuals from start up Mirtazapine treatment, I wonder if it is 5HT2B related?
I don't understand what you mean about the 5HT2B receptor, though? AFAIK, very little is known about the receptor. Even if agonizing 5HT2B was a good thing for empathy, it's a bad thing for your health if you are an individual who is prone to cardiac issues. I think people generally avoid 5HT2B agonists for this reason.
Wow, you take American Ginseng with Yohimbe? Yohimbe will be even more probelmatic than Yohimbine in terms of side effects. Is American Ginseng quite mellow? Panax Ginseng gives me a raised heart rate (it's literally thumping through my chest). Yohimbine does the same thing (to a lesser degree, at 2.5mg), albeit with heart palpitations thrown into the mix. I would be scared to mix Panax with Yohimbine, in all honesty. SJW mixed with Maca (taken chronically) was another 'heart disaster', and something I don't care to repeat.
I think I remember reading that American Ginseng was a more mellow version of Panax, I wonder if it comes with the same benefits (minus the anxiety)?
There are things very unique to Panax though, which give it its antidepressant effects. There is a study I can dig up showing it fuses with 5HT2A agonists (5HT2A antagonists block the effects). I also have a paper showing it to have indirect NMDA potentiating effects, and GABA-A effects (this doesn't surpise me as, although it is very stimulating, it has a paradoxical calming effect which is always present in the background, probably why it's not something that is generally hard to sleep on unless you take it too late in the day). 5HT2A agonism will release glutamate, DA and oxytocin.
Anecdotally, I can confirm that my brain feels alive on Panax. My memory is much better (especially working memory), concentration/focus improve, my mood improves drastically (it does feel serotonergic, but in a raw stimulating way), my libido improves (it improves adrenal function, like most adaptogens), i do indeed become more empathetic (my emotions come back stronger, but not in a soppy way) and erectile function is enhanced (it improves blood flow considerably around the body).
The only one major downside to it is it is way too stimulating at times, to the point of being anxiogenic (but I've only noticed this in panic type situations). Panax, for me, is the cure, but I need to find a functioning GABAergic agent to use alongside it to tame this side effect. Or, just not take it when I know I am going to be in a potential situation of panic (for me, this is mostly based around talking in front of groups of people).
