I usually get by on 5 to 6-hour sleep when I am in London, Anne. But, I nap on the weekends when I am home.

I actually thought I have got my sleeping pattern down to pat, Saundra. Until fairly recently...it's similar to yours. I'd have nights which are fine and then, there are nights when I'd have only two hours of sleep. I get so physically sapped when those two-hour sleeptime come in succession. So, I just take home work so I can nap when sleep comes in the daytime. This menopause malarkey is such a bummer. I'm hot flushing/flashing as well. I was over all this business for a few months but, doggone it...iiiiiit's baaaaaack!

That's what I do, Chatty. I get up from bed and read until my eyes tire or, turn the telly on.
