Why is it when you are tired and want to sleep, Sleep is the last thing that comes your way. The experts say try a cool dark room, check; with the exception of my spouse's habit of channel surfing. Quiet your mind, I have one question on this suggestion, HOW???? Get into a regular routine "they" say, do "they" have children, pets, a spouse, parents, jobs, school, homes...(you get the idea). Never oversleep, not a real option when you take medication to get you some sleep and you can't hear the alarm the next day. Don't NAP, but what about all the effort to get us to take a power nap? The only suggestion I found that seems to have some merit is this one, if you find you are only sleeping about 6 hours and getting up at 7 don't go to bed before 1 in the morning and this is supposed to help with the frustration of tossing and turning.
Sorry to vent, but I am getting cranky after several restless nights.
