After5 - Welcome to SR. Your story is mine, almost exactly.
My recommendation to decide if you are an alcoholic is as follows:
Try to have no more than 2 drinks in any one night and try not to drink more than 4 nights in a week. Do this for two weeks.
(And 2 drinks = 3 ounces of whiskey, not the two eight-ounce glasses I used to call two drinks)
Be honest with yourself. See how you do.
This will help you decide.
