Want Sleep

I've been sleeping badly for the last couple of weeks - having trouble falling asleep, and waking up at every little sound all night, along with overheating and having ridiculous dreams. I'm so exhausted . . . I'm going around constantly with that gritty fatigued feeling, yawning constantly and tripping over things all the time. I don't know what to do. I can't get a doctor's appointment until Monday and I feel like I'll be completely insane by then. Herbal sleepy thingies don't work for me and I haven't even got any drowsy cough medicine I could take once or twice to get myself back on track. I keep trying to go to bed but I just lie there for hours and hours without falling asleep. It's been happening since daylight savings time started but I don't know if that caused it or if it's part of a larger problem . . . *sigh*
