Mark, thanks for the response. I did not know that it can induce psychosis. It's probably something not for me as I have schizoaffective disorder and already have some hallucinations at night in my quiet dark room. I'd rather not trigger a psychotic break and end up in the hospital...again.

CenterIce, I also thought that this would be very valuable in the early stages of recovery. Thanks for the links. I'm content with earplugs for now. I do have some noise cancelling headphones that my dad uses on the lawnmower.

davOD, I also think most clearly in my room. It's amazing what shutting down a few senses can do. I've heard good stories about float tanks, but that's because I was searching only for good stories.
