You are not alone. I was exhausted last night. Went to bed at 10:00 and fought with the cpap machine until 11:30. Got up and watched an episode of Chopped. It's on the Food Channel. Went back to bed and could not sleep. But I am exhausted. Finally dropped off around 4:00. Had to get up at 6:30. I can't go with the flow. I am still teaching. I am also having a problem in that every morning when I get up I am experiencing what I think are bronchial spasms for 5 to 10 minutes. I think they are allergy induced. I have been taking ambien for about 3 years and it never worked great. But now it does not seem to be working at all. None of the drugs that are supposed to be sedating seem to help me sleep.
