I only did about 4 small bumps and I was drinking a lot of beer at the time as well and it was less than 48 hours ago! I don't do coke on a regular basis but i have a lot of friends who do, so I do it maybe once every 3 or 4 months at most. I was NOT thinking, I was really drunk and it was offered and I'm so scared that they'll cancel the surgery!!! HELP seriously, I'm really scared!
