Welcome to our alcoholism forum.
I too suggest making an appointment with your physician. Remember though that the best way to get help is to be completely honest with your physician. Medical professionals deal with alcoholism/drug addiction on a regular basis. They can be your alli in finding a solution. But if you do not provide them with a clear picture of what is going on then they can not make as accurate of a diagnosis.
Just the fact that you feel you have possibly been drinking enough to have developed liver problems is a sign that you are probably drinking more than the normal drinker would. A good health checkup and honesty with your doctor can provide you with some answers to the health questions as well as refer you to resources to find help for the drinking if you choose to do that.
Hope to see an update soon from you and I sincerely hope it is good news from the doc.
