If you have Bette Davis Eyes because you just cannot get to sleep at night, I have a little trick one of my home health patients told me about.
Have your bedroom a little cool. Go to bed but do not cover up. Get really chilled and then cover up. After you get all warm and snuggly, you will drift right off.
I usually sleep very well and only have three or four sleepless nights a year. When I do, I try this and it works very well.
