Here's a tip guy. We all go through things. Few of us are brave enough to share even when drunk. Walk in with your head up and pretend like nothing even happened. If people bring it up just smile, laugh it off and say GD yea man... that scotch he brought was just way too nice. I didn't even notice it going down. Then if you want to take the cowards way out just say you know you started acting weird but don't really remember many details. Everyone relates to you more than you think. Try it out.
