Last Thursday night I went to bed at normal time (around 11), but woke at 4 am feeling really queasy. I got up and proceeded to throw up. Rar. I went back to bed, but was still feeling woozy. Eventually I went to my own bed because I could tell that I wasn't done being sick. It turned out that I had a really bad stomach bug and didn't manage to eat anything until dinner on Friday (white rice with a little butter) so I could take ibuprofen (I had a fever of 101 when I got around to checking it). And then I went back to bed. Until Saturday at 10 am. I woke up from time to time during this crazy 35 hour stretch, but not for longer than 30 minutes. I was awake until about 10 pm on Saturday and then slept until 8 on Sunday.
I hope that doesn't happen again for a long time!
