I don't know what's happened to me since thanksgiving, but I have not been able to sleep. I don't know if it's due to stress (finals and going to South America in about 4 weeks) or what, but all I can do is toss and turn at night. I don't know if I've gotten my internal clock off base and a few sleeping pills a few days in a row could straighten me out or not.... this is driving me crazy..... writing this as of 5:40 AM Thursday morning.... been trying to fall asleep since 11:30 last night.... please give any advice if you can.
