I think it would be a problem if the ONLY time you felt better was when you're schnockered. Or, if the alcohol itself acted as a depressant, afterward.
Everyone needs to turn loose occasionally, don't worry about that- it sounds like you know how to self-comfort productively.
But if you ever feel like you need a doctor, don't hesitate. Brains are complex, and sometimes need a kick in the lobe to work better.
You are so smart!
