For me coffee is way more dangerous than methylphenidate in terms of psychosis. Methylphenidate actually helps.

You're on amphetamine but that didn't do much for me but my psychiatrist said that the prozac made the blood concentration so high and even though I didn't get much of a therapeutic effect, I don't remember those 10 days that I stayed in bed for when he took me off cold turkey saying I must feel like I'm on crack.. but I said crack didn't do much either though but coke is like ritalin I prefer ritalin.. :/
