I've only once used caapi and it worked very well. I brewed 30gr. of white caapi and drank the tea. Then I was just lying in the bedroom sofa for hours very relaxed and hearing sounds in distance that I would never have picked up. Had a bit scrambled sight also and got a bit nauseous but not enough to throw up.

The next week I was very high on life and my senses were stronger. Music sounded better and I felt very good in general

This was around a year ago and I'm doing this again soon. Just need to find the time
