I was on Geodon(aka ziprasidone) & celexa 5 years ago and at the time it didn't seem like it worked. I still had SP, but I also had a job, I talked to people, & I made a good friend. I went off it after thinking I was cured, the years that followed were the worst of my life, alcoholism, deep depression, and my now hermit life.
The things I did when I was on it seem impossible to me now. Meds are more of a helping hand than a cure.
I've heard some horror stories of antipsychotics involving a permanent condition called tardive dyskinesia(involuntary twitches) so i'm weary of taking it again. I might try seroquel, it's supposed to have less of a risk rate.
I believe SP itself has underlying causes, mine being an overly paranoid personality, antipsychotics help that by doing something to the dopamine area of the brain.
