Between mescaline and psilocybin. I have only tried psilocybin, and I'm hoping people who've tried both in the form of tea (in both high and low doses preferrably) and eaten raw (peyote and mushrooms) could inform me of their personal experiences with both substances.

i can tell you mescalin tea is way more nauseating than dried or fresh mushrooms.

I rarely ever get nausea from mushrooms (in any form). With mescaline, it is pretty much guaranteed that I'm going to puke around that 2-3hr mark, especially if it is tea.

My vote is for mescaline being more nauseating.

Is it worth it however? The nausea? Or do you prefer mushrooms both because of lesser chance of nausea and better insight and healing overall?

It really depends on who you ask. Mescaline is wonderful, definitely worth experiencing!

Post-purge is the best part of the mescaline experience, imo. It can be rocky for the first couple hours during the come up but cannabis can help you(me) keep it down. After about 2-3 hours you'll likely get very nauseous and purge anyway. Sometimes sooner (for example, my gf usually purges within 1-1.5 hours on mescaline).

If you purge, you purge, if you don't, you don't. That's the way I try to look at it. Cannabis and ginger are your friends when it comes to calming an upset stomach.

Fasting at least 24 hours before an experience (on any psychedelic) can help reduce nausea too.

Mushrooms have been my "go to" psychedelic for quite some time. However, after a particularly intense mescaline experience, I became thoroughly impressed with cactus and picked up a few bridgesii to grow and care for. This Spring/Summer will be their second season with me.

The point is that neither mushrooms nor cactus are inherently better than one another, from an experience standpoint. Both have the potential for Nausea but it is more common with cactus/mescaline, ime/imo.

Thank you so much for elaborating. I am also wondering if the nausea can be painful. The most painful nausea I've experienced with psychedelics was with a syrian rue + dmt tea. It actually hurt to vomit. That was however the only unpleasant part of the experience as when the nausea was over it was magical. When I get nausea with psilocybin it's usually easygoing and painless, I even laugh sometimes during the process.
