LIke someone said. " If I had known grandchildren were this much fun, I would have had them first."

Sound like you are an owl, have difficulty getting to sleep, but then have difficulty waking up. You are not alone.

When my alarm goes off in the morning I am usually the most comfortable and in the best sleep of the night!

Have fun with the kids. I have started to wonder why it is that we do not suffer the things our bodies give us when we are young and can deal with it better, leaving our later yeas without the pain and frustration we now have. I am really hurting today, so I am preoccupied.

I also have insomnia.
I usually get up for an hour (read a book, 'surf' agnostic, etc.) then am able to get a couple more hours of sleep.

I have tried Melatonin with mixed results.
