I've been so sick so many times after drinking pseudo-jägerbombs (red bull isn't sold in Denmark, as it's considered "too strong" - meanwhile, 11,5% beer is no problem

). It never fails in giving me complete blackouts and the worst hangovers.
Today is Monday, and I'm still shaking like I suffer from Alzheimer's after a birthday party on Saturday. I had a six-pack of fairly strong beer (Ceres Royal Export, 5.6%) along with a few pints of cider (Swedish Kopparsberg, 4-5-ish %), at which point I decided to take a quick break and head to McDonald's for a quick snack with a friend. Worst idea ever. We got back, I had half a cider and went and spewed it all over someone's front door. After that, I felt like shit, but thought I might as well try and get proper hammered, and so I did. Within the next hour I consumed 3 liters of cider and one liter of gin & tonic, along with with any shots that were within reach. I woke up at 6 in the morning on a couch, and someone passed me a joint. Skip forward through 3-4 hours of sleep, and it was time to head home. I could barely stay awake for the 1½hr drive, and spent all of Sunday on my couch. more than 24hrs later, I still feel a bit smashed, and going through the whole "I'll never drink again" thing...
Gotta love it.
