I agree with Phoenix and Tim - Be honest with your doctor about your addiction and follow his advice.
When I got sober, I was taking Celexa and Klonopin for anxiety. My doctor (who dealt alot with addictive medicine) took me right off the Klonopin - which, of course, was doing the best job of managing the anxiety.
Like you, I went through big time mood swings and was generally unpleasant to be around for several weeks. But it gets better. With me, I had to learn to cope without the booze crutch to relieve stress.
"Like all things, this too shall pass." Your situation will get better. You're doing the right thing.
I hope this is of some use or comfort to you. Congrats on your time.
Good luck and God Bless.
