Yes when I was psychotic I couldn't sleep more than 2 hours a night for like a month and I still occasionally have issues where I don't sleep but I don't get tired either....luckily it mostly cleared up once I got the voices under control. I still have trouble waking up too early like 4 am and it seems to pattern with stress...I'm kind of expecting it tomorrow given how today was. We shall see if the pattern continues. One thing my pdoc recommended as a test was melatonin it's a natural supplement that your body makes so it's pretty harmless compared to the prescription sleep meds so he wanted me to try that first.
