So after some mixing of champagne and vodka (in separate glasses of course) I felt sick. Of course I didn't realize I was until we left..
Well right after we left we went to my friend's friend's place for awhile..then as we were leaving I could barely walk because I felt SO light-headed =\ Luckily I made it back home around 4am, slept on my desk until 6am, and woke up feeling totally fine and no hangover.
