I just completed my third full spectrum level 3 brigesii trip yesterday, which is something like my 15th mescaline trip overall. It was from an everclear extraction, dried to resin and capsulated, which I happily found causes no nausea or vomiting. I've begun to notice two side effects that are common to all of my full spectrum trips:

1. A persistent choking cough.
2. The forced flexing of leg and abdomen muscles.

Is there any way to eliminate these? Will an isolated mescaline extract solve either of these? I'm wondering if it is one of the other alkaloids that is causing them. The trips are wonderful, but could be a lot better without these symptoms.

I don't think these side effects are usual with full spectrum extracts. Never happened to me.
You had 15 experiences with full spectrum and had these side effects each time ?
Never did an ethanol extract of it though, only water extract reduced or not, drytek/limteks or the like with lye base then limo or xylene pulls and salting with diluted HCL.

If you can extract near pure mescaline crystals.. your trip will have almost no body load and much cleaner experiance...
Full spectrum can have other effects..

Yeah, I've done raw, tea, and everclear extract, each multiple times. In light trips it is barely noticeable or nonexistent. Moderate trips are where it starts to become noticeable. In the beginning, it didn't bother me so much, because my raw and tea experiments were so weak, but when I got to brigesii and the everclear extract, the trips AND the side effects became much more pronounced. Twelve hours of random, uncontrollable coughing fits and muscle clenching gets annoying to the point where I'd rather not be tripping just to make it stop.

I'm working on my second limonene extraction attempt now. Trying to figure out the best way to evaporate the vinegar without oxidizing the mescaline, which appears to be the biggest problem with obtaining a dry material. I assume that's where I failed last time. I'd just leave it in the vinegar to preserve it as much as possible, but I want to purify it with MEK which seems to require a dry material. I'm hoping that a pure extract will eliminate the side effects.

So that's my challenge right now: how to dry the full spectrum mescaline without turning it into an oxidated, inactive mess.

Thanks, that's what I'm looking for. The body load at higher levels is so awful that I won't be able to proceed further. I'd like to go further.
