Hope you pass through the insomnia time.
I find even some light stretching exercises 1-2 hrs. before I go to bed helps me relax and fall asleep faster.

If you choose the right exercises, you will also be less prone to aches and pains in general.

I know, I did post on being sleep-deprived...but that's from not going to bed early enough and getting up too early ('cause I have to).

I have been falling asleep within 15 min. of hitting the pillow for awhile.

Have never taken sleeping pills in my life....though have gone through times of stress that's kept me awake.
