Zyprexa made me also gain weight rapidly but has worked as one of the best antipsychotics for me. Keep in mind though, I have a history of hallucinations and delusions.
Unfortunately, I'm currently trying to get off my Zyprexa (last dose was Wednesday) and although my appetite has now returned to normal, I've become concerned that some psychotic symptoms may be appearing again.

AP's can be a wonderful drug but they can also be hell to get off of; I agree with the above comments, 3 AP's seems a tad excessive.
