I've taken 2ct7 once at 50 mgs, it's funny you mentioned mescaline there because 2ct7 had a very strong mescaline component in the feeling and headspace but the visuals were a bit more 'zany' or silly, a bit like acid. I had persistent nausea on and off throughout the trip but it was bearable. It's a long trip, it lasted a full 12 hrs for me and I went to sleep still kind of tripping.
I should enjoy it then, I'm a huge fan of mescaline. I thought about having around 30 mg the first time before indulging in a massive 50-60 mg dose. Ahah I'm a bit of a daredevil, I like to push myself up to the limits of what I can handle, but maybe not at my first experience with a new substance.
