Alcoholism is a very serious but very treatable disorder. If you suspect you might be developing alcoholism there is no shame in seeking advice from a medical professional. It doesn't sound like you have a problem with your drinking but having a professional diagnose if this can turn into a problem is a good precaution if you suspect you might get sick.

A common myth about alcoholism is that it is a personality trait, and people who are alcoholics will always be one. This is incorrect. It is a disorder that one develops and is treatable. If untreated one can be sick for the rest of ones life. The consequences can be severe, including the loss of your job and even your family.

As said before, it doesn't sound like you are terribly sick. A good thing to know is that you are not alone. Many people have this disorder and are actively seeking help. As with other disorders, a professional opinion is always better then self diagnostic.
