Out of interest, if you use antipsychotics for a long time, how hard is it then (once you quit) to lose the weight you gained on them? Is it possible at all? Or is the weight gain somehow diet-resistant and almost impossible to shed, the longer you have taken antipsychotics? Would appreciate responses from someone who knows about the subject.

On the other hand, is it possible to get rid of side effects a year or so after stopping use of antipsychotics, or do the side effects always come back once one has started using them and then stopped (this includes hallucinations in its own right, for example)?
