Lots of people on the forums have mentioned trouble sleeping. I've found that I NEED to have a fan blowing no matter if I'm hot or cold, I just need the air movement it provides. It has gotten to the point that I have a small fan that I intend to take with me whenever I travel for just this reason.
The fan has an added benefit of adding white noise, but recently I started going to RainyMood.com on my palm computer and letting it run over night while the I'm sleeping and the sounds of a rain storm seem to help me sleep.
