Thanks so much for posting, I am so glad you are taking the steps to get better. I am also so glad you are going to talk to your doctor, make sure to tell him everything (how much you drink, what other drugs you use, etc.etc.)
The doctors really need to know everything to make a accurate diagnosis.
If you feel embarrassed to talk to this doctor (for any reason) about everything, see if you can get a referral to another doctor.
Congratulations again on working towards getting better!
