aMT for me was the most gentle psychedelic I've tried. That doesn't necessarily mean the experience is weak or lacking in intensity, just I felt like nothing could go wrong, it felt very easy to handle, friendly, easy to work with. It felt like my mind liked the drug and didn't feel threatened at all by it, much like with empathogens - but not like certain other psychedelics are for me.
On the body it wasn't as gentle, with 50mg of the freebase taken orally I threw up on the come up, and the second time I took it (75mg, but with tolerance) I didn't throw up but I still felt quite nauseous from around 1 hour in to 1 hour 30, maybe 2 hours in. However, it was very much worth it for me, and both when I threw up the first time and when the nausea naturally subsided the second time I felt like my body released a huge burden, it felt very much like a nice purge rather than "Oh god I'm tripping and throwing up what oh no!"
