Usually, half of my day is spent in bed as I can't wake up, and I can't go to sleep.
Basically, I set my alarm for something like 7am. I then sleep right through, don't wake up until about 11 or so, then I finally get up around 12. Then, when I try to go to bed around 10, I don't actually get to sleep until maybe 12 or 1am.
However, lately I've been taking melatonin, which is actually making me sleep and wake up when I want to, so my days have been much better.
