A lot of people experiment with drugs and drinking sometime in their life. There is nothing wrong with going through phases and experimenting for awhile. The only thing that seems unusual is your own concern whether or not you will be able to stop drinking. Don't lose or ignore that concern. If you don't think you can beat the drinking desire, then get some help.
I have been close to a person that had a drinking problem and they had a huge denial problem. You clearly have good awareness of yourself and situation, which is half the battle with an addiction. You seem to have a good head on your shoulders.
