HI feellikealoser - welcome
I'm glad you found SR - it's a great place for support. I can relate to your posts - I felt like I was in a big hole, trapped by alcohol, with no way out (self-employed, couldn't afford to go to treatment, etc). But thanks to the support here, I've been sober over a month now.
I thought I was functional, too (no one really knew about my problem and I didn't lose a job, family, etc), but now that I look back on it, I wasn't functioning very well at all. I was miserable and walking a fine line in alot of respects, including my health.
I think everyone is right about going to your doctor (or finding one that specializes in addiction/detox if you can). As you probably suspect, the combination of alcohol and drugs can make for a dangerous withdrawal.
If we can do it, you can do this too. A new life awaits you!:day6
