Cuppy cake, just reading this post gives me shivers. I'm not sure if your bf's experiences are similar to the ones I had during my heavy using time, but it sure sounds like it. Although I didn't drink too much I was a heavy crack user and I can remember the voices in my head of those close to me. After being on a 3 or 4 day binge I can recall specific instances where I would be in a grocery store or hiding in my bathroom and hear whispers from my wife and kids and even parents. It would drive me crazy thinking they were in the next isle over whispering goodbyes or other hurting remarks about me. Although i have heard stories about seeing people that arent there "shadow people, dream police" and other hallucinations I have never heard anything that mirrorred an aspect of my experience so much. I dont know if this helps you much considering the difference in DOC, but it has stirred some feelings for me. I never wanna feel that paranoid or out of touch again, thanks for the reminder.
