Hey - we're up for New Year's Eve round-the-world talkathon!
Being no-longer-young foodies, we usually go to bed about 9:45 (local) on New year's Eve, but with sufficient alcoholic bracing, could probably last for some time.
Once, when I was in the Navy, I was awakened at 2AM on a Tuesday morning to help run a search for a Russian nuclear sub, and didn't get to sleep again until about 4PM the following Friday. I couldn't do that again, but I could try.
