Coffee works and I can suck it down all day again. Alcohol works too, although I tend to avoid it since I was using it as a depressive agent to try to stop my second psychosis. I can enjoy a glass of wine and feel nice with dinner. I am not a big marijuana user, but I did hang out with some old friends a couple of months ago and smoked some on a hike. It did get my thoughts on a lot of psychosis tracks, but i was able to successfully avoid those, although a lot of enjoyment was lost in having to do this. I did also have moments of reset perspectives and wonder just like in my old smoking days as a youngster ( I'm 33 now). Wow, and that shit sure is different now that it's legal in WA. For effectiveness, I would say 100%. If you've had psychosis, I'd say watch the hell out, although I could see paths to training and reasoning your brain out of off track lines of thinking, within reason.
