I've just come back to school after a winter break of perfect sleep. Last semester I was having sleep problems too, but it seemed like after my perfect sleep at home (and I also slept perfectly in 2 other beds besides my own) that my sleep troubles should be over. I've kept regular sleeping times too. But I cannot fall asleep until my roommate does. Even then I get up a few times in the middle of the night, even when it's not noisy. I think it may be because they changed the air conditioning to heat. Ever since they did that I couldn't sleep here. (When it was still air conditioning, I could even sleep before my roommate went to sleep!) We keep the heater off so that it's not too hot, but I need some kind of white noise to sleep, which the air conditioner provided... but now I can't have that because it will be too hot. I have a small fan, but that doesn't help me very much. I can only sleep if I take sleeping pills (Simply Sleep by the makers of Tylenol PM) ... but I don't think I should be taking them every night. Any suggestions?
