In that case just be careful, one or two drinks a month is really nothing to be worried about BUT I think it's good to pay attention to your conscious. Obviously its a concern if you had used alcohol to self medicate before. Listen to that instinct.

Also I encourage you to consider this: If you're only having a couple drinks in a month, what are you really getting out of it? Why not just stop drinking all together? You won't be missing much.
