Risperdal/Risperidone --> antipsychotic

I'm taking 1 mg Risperdal + a couple of other meds. It was prescibed for me for depersonalization, no psychotic symptoms or hallucinations here. For me it has brought relief and no side effects other than constant hunger, which I'll just have to ignore..so Ziggomatix has a point there :?. Without this med I'm pretty much unable to function, but I still feel dp:d. I used to be very afraid of anti-psychotics but for me they've so far caused no harm.
