You know....like I'm going to be the shiny beacon of sobriety in a group of pro drinkers dying to have a good time! (Joy kill). Lol

I would gracefully hold my drink...fein a sip...then excuse myself to the bathroom and fix the drink to my needs...then go have fun. After the first cup you are accepted....just keep sipping water out of the beer pong cup and still have fun! Good luck.
