Insomnia

I've had insomnia for a while, but these last 2 weeks, it's gotten a lot worse. I spend 11 hours in bed, but sleep only about half that time. Wake up, fall asleep, wake up, fall asleep....... Now I'm falling asleep in the late afternoon or early evening. I'm miserable, have a mild headache most of the time, and I'm tired all of the time. I'm really looking forward to my next Dr appointment next week. I just hope my Dr has a solution for my insomnia, because since the deviation is getting worse, the insomnia will keep getting worse.
