I was thinking schizophrenia when i 1st started reading it but at the end it goes " But now I've changed and I'm attending regularly." You do not just change, unless u are doing something to cause it. So he's on some good sh*t shocked

sry i was just sayin he is probally doing estacy, it brightens up ur senses like touching, hearing, seeing the stroke lights at clubs etc. Anxiety and hallucination that is not specific and alot of different drugs give u that.

But i dnt understand did this patient have these symptoms AFTER he "changed" his habits because then it might be DT from alcohol withdraw but then again it says Acute.. so maybe not lol

It is def not schizophrenia.
