Beginning last Sunday, I began to have sleeping problems. I just seem to stay awake the whole night. My body is extremely tired (and sore) but my mind just keeps going on and on... and keeps me awake. It's kinda strange that sometimes I feel extremely hot and don't feel comfortable at all (even though it's quite cold outside). I usually go to bed at around 11 or 12. Right now, it's 5:20 a.m. and I'm hopelessly awake. Ive almost wanted to hit my head against the wall or something so I can get some rest. I've tried various things the past couple days (in combinations): listen to music, different relaxation methods (deep breathing, counting sheeps...), go to bed early, take a warm shower before bed, read some extremely technical books (like things to do with knot theory that I know zero about), think about really hard problems to try to get tired...etc, I feel I might've slept for like 5 minutes just before after thinking something about gauge transformation but then it doesn't work again. People say this is a bad idea but it seems to have some benefits. Anyway, none of these really work. I exercised sometime before going to bed on Tuesday night and that was the only day this week that I got good sleep (good 10 hours). I exercised yesterday night but got nothing this time. Like yesterday, I pretty much stayed awake the whole night and had to sleep from 2 p.m. - 6 p.m. after coming back from school. I don't know what's happening to me. It just begins this week and I am scared that this pattern is here to stay... right now I am just going to do my homework and all my plans tomorrow are pretty much canceled since I know I'll be extremely tired at around 9:00 this morning. My schedule is completely wacked due to this problem. Good thing that class works have been relatively lower this week--but not for long. What can I do? has this ever happened to you? I really don't want to take sleeping pills or go to the doctor but I guess I'll have to do so if it continues... Any comment is appreciated.
