"What's helped me the most so far is realizing that every hallucination is like a bowel movement: It's a bunch of processed waste your body is trying to get rid of. You may not be able to identify what each hallucination originated from (what you 'ate'), but you can control what your emotional state is, and thus how your 'turd' smells. Everything you see comes from within you, so ask yourself "Why would that be the natural result of my psychosis?""
