Be careful with all of that, you should consider being under the direct supervision of a physician while you do this detox... self medicating ain't good. I know this to be true from personal experience. It wasn't until I was under supervision (Wow, I am such an independent minded person I hate even typing that word!!) that I was able to get free of all that crap... pills, alcohol.
Reach out and ask for help. Sounds like you've got nothing to lose and everything (your life) to gain!!
