Ever slept on and off through a whole day??

oh yes. i used to EVERY saturday for a few months...only saturday's though, not sunday's. but yes, i'd get up, eat breakfast, go to sleep, then get up, eat lunch, go to sleep, sometimes sleep thru dinner, get up watch a 30 minute sitcom, then fall right back asleep. i thought it was depression at one point, but it was like my body really just needed some time....and i haven't done that for awhile, so i bet i was just playing catch-up. but it was a waste of day. it was strange.

The most I have ever slept in one day was 18 hours.Actually it was only 12 hours of sleeping straight then I woke up just to ate then slept back for another 6 hours.

Yes, I have. When I stayed awake for pretty much like 3 days straight and kept going with a few little "naps" on like the 3rd and 4th day. By the 5th day I was so exhausted I wanted to collapse, I went to bed, didnt even look at the clock because I was that tired! I had to of slept a good 12 hours, and took it easy the whole day, just laying around and watching movies and stuff. Your body because more tired as you sleep more, notice when you sleep 10-12 hours as opposed to 7-8 hours, your body becomes more tired after getting so much sleep, I dont know why this is though!
