Man, there is hardly any adult on the planet that hasn't done something they regret whilst under the influence of a little too much alcohol.
Don't be too hard on yourself. If you upset someone else, try to apologize and if they have any kind of empathy they'll understand.
But first and foremost, forgive yourself. We all do it and we're all still here to tell the tale (although I'm not telling mine as they're WAY to embarrassing!)
