When going dry it is extremely important that you make an appointment with your medical doctor ASAP. Then, once at the doctor, be completely honest with him/her. Tell them how much you drank, and how long you have been sober.
Remember, doctors must be confidential so it's not like they are going to broadcast how much you drank. The first step is being honest with yourself.
I suggest you check out a recovery program. I personally am in AA.
