I take choline every day in the morning and at night which I believe is considered to be a light nootropic (it has definitely helped my cognition over the years). I tend to always have very long mescaline trips paired with little confusion and a lot of visuals. These trips are always very jovial, happy, and deep for me, although I usually vomit a few hours in.
I'm afraid I cannot compare mescaline with no choline as I have been taking it every day for many years, so I don't think I've taken any drug ever without having done choline that day with a few exceptions for DMT and maybe marijuana.
