I once was more or less wasted for 36 hours straight. It was the only time I've ever drank in moderation, but that was only so I wouldn't pass out at 11 pm as I usually do. But yeah, the basics of it was that we drank, went to the sauna, did some waterskiing, swimming etc. Then ate and drank coffee, drank more, sat about for a while, went to the sauna again, swam some more. Basically like that the whole 36 hours. Some didn't make it and passed out at around the 18 hour mark, but they got up and started going again after a few hours. I slept for roughly a 20 hours per day for a week after that.
Most adults called us idiots, others called us heroes. Hot damn it was fun though.
