Sleep worked for me when I had a major manic episode. My doctor tried to stop it by adding mood stabilizers and a second antipsychotic, but those didn't slow me down at all. I kept on going while building up a real sleep deficit from sleeping very little. I got so mad about my pdoc wanting me in the hospital that I ingested an entire package of free Risperdal samples from my pdoc. My parents called my pdoc concerned about me consuming all that Risperdal. She told them to let me do that, because it might finally put me to sleep. I awoke 14 hours later in a miserable depression. The mania disappeared completely.
