I average 6 hours a night, and I find I need less and less sleep as I age. My theory is: sleep is for the very, very young and the very, very old. I like going on less sleep, it means there's more time to do other stuff!!
I have just prayed for you Donna. I'm so sorry to hear things hard for you, but thank goodness I found where you have been posting, I've missed you.
