Drunk and stupid don't really mix. And often, they go hand in hand. Honestly, I don't know how anyone lives with themselves after that.
On a side note, drunk and stupid most certainly go hand in hand for me. Luckily I never hurt anyone or myself... well other than the debilitating hangovers and withdrawals, and lack of productivity at work. Took a swing at my brother once, we were both drunk. Still regret that.
