I vented yesterday about not being able to sleep except for a couple hours. Last night the same thing started happening. Even though I passed out at 9:30, I was wide awake at 11:30. I tried a relaxation "song" I have on my ipod and nothing. I was a little hot and thought that could be the problem so I turned our AC on. Within the hour it was so cold that I was all wrapped up warm in blankets for the first time in month. I slept well for the rest of the night (still off and on but never fully awake for more than a few minutes).
Moral of the story: In order to sleep turn bedroom into a meat locker. Sorry DH time to pull out the flannels.
