Never drink and drive. The one time I did it, I nearly hit a parked car when I was doing 75mph. Missed it by INCHES! That was my warning, wake-up call, kind of lesson. I am hungover because I didn't eat anything before I drank, but I only had 4 drinks starting at 5:00 and ending at 2:00am.
Nasty little bugger headache... practically bans myself from looking at the screen!
