i agree self-dx. by reading over the internet just can make you think you have every symptom.
Go to your doctor, tell them HOW MUCH you drank X how many years and they will run the proper tests at intervals (usually 90 days apart, maybe 4-5 months). follow a good nutrition plan and try to get yourself back into a positive frame of mind.
why 2nd guess and dx yourself with something you probably do not have. Leave that to the professionals.
