I recently had a psychotic break and was in the hospital and the doc is being paranoid about rx'ing me adderall, which quite frankly was the miracle drug for me.
I don't smoke, but I decided to eat 1/3 a cigarette and got a buzz similar to a 14mg nicotine patch, which was a bit strong for me, but it seems to work...killed my appetite and allowed me to focus.
I know it can't be healthy to parachute tobacco from a pack of cigarettes but my brain does work better on nicotine than on caffeine...it's just temporary til next month when my original doctor is available who I'm sure would still give me adderall or some other Rx ADHD med.
ADHD is really debilitating, moreso than schizo stuff unless I'm outright manic or psychotic, which usually is triggered by acute stress, like being in the hospital for other medical issues.
