rubylady that's sad about your friend. Don't worry about what to say, they will know there is nothing. Just be there, hold their hand, talk about nothing, read something to them - poetry, the newspaper maybe. Tell them something funny that's happened in your life, even if it was years ago - try to bring a smile to their face. Good luck 
Well I woke up at 2.30 to go to the loo, nightie drenched with a night sweat, as was the bottom sheet, so changed nightie, laid clean towel over damp sheet, tried to go back to sleep but couldn't. Why have I started getting night sweats again at nearly 66? I had a hysterectomy 23 years ago, was on HRT for 4 years and then came off it. I thought all this night sweat business was well in the past, but it's recently been plaguing me
