I have been going through this myself for about 10 years MDs really are useless at helping. Right now I've had 1.5 hours sleep out of the last 36 hours, even taking 3 different meds that should knock me out has no effect.

The best thing I have found to work for me in the past is to be as physically active during the day for as long as possible and forcing myself to stay awake for 16-18 hours straight. Then I watch about 1/2 hour of TV to unwind and I would be quite sleepy by then. The last time I tried this I got almost 5 hours straight sleep.

There are literally dozens of things to try, I have just given you one way. I hope it might work for you. If you do try it please let us know if worked or not.

I'm sure some more suggestions will pop up here soon.
