schizophrenia
"Clears the mind of weird thoughts, delusions and hallucinations. Weight gain has been noted as well as a general feeling of restlessness and drowsiness. I'm always on slow-motion and need to think things twice or 3 times. Still better than having conversations with dead people or thinking my brain can see in the future... by the way, DON'T try quitting this drug cold turkey. It's a recipe for disaster."
