Thanks, I feel better today. It seems to alternate. One day I feel so exhausted that I can barely think and the next day I feel good. It also might be related to sunshine, but I don't know why, because I work all day in an office with no windows.

Another thing I am trying is to drink some licorice tea before going to sleep. Licorice has some antidepressant chemicals. It seems to help me sleep without waking up every 30 minutes, but I'm not sure. Maybe I sleep better after a bad night of sleep because I am so exhausted. (I used the licorice teas last night, and I only woke up a couple of times.)

You might try the licorice tea and see if it works. It might have drug interactions depending on your medications, so you ought to check that first.
