I used to have a problem with alcohol for a few years. I'd drink like 4-5 huge drinks every night, technically closer to 8 official drinks. So I was dual diagnosis too, but I managed to get off drinking with worrying about how my meds would interact with them and my liver. It's only been since October of last year that I stopped drinking regularly. It's a temptation on really bad days, but on good days too sometimes I think...I would feel even better with a drink right now. I drink mostly when I'm happy, not sad. But I feel the urge to drink when I feel terrible because I want to feel differently and anything has to be better, right? Don't have any experience with cocaine, but I understand why people use drugs. Because they make you feel better or different at least for a while. That's what our meds are supposed to do, but when they're not working, it's the easiest thing to want to go back to what we thought did work, although the repercussions are dreadful. Don't give up the fight. I'm sure there are meds out there that can curb your cravings. I know my doc found one for me after 2 years of trying and now I feel so normal, I don't even want to drink. Good luck in your quest. We're here for you for support whenever you need it.
