Usually doctors will prescribe low doses of anti-psychotics for patients who aren't psychotic. High doses are usually only necessary for schizophrenics. So, the weight gain might not be that substantial if you stay that long on that small dose. I took .25 mg of Risperdal for a little while. It didn't do that much except the fist night I took it, I felt like committing suicide, but only that first night did it do that. My doctor told me that meant I wasn't psychotic b/c most schizophrenics feel good with their first dose and non-psychotic people feel like crap.
