My mum aged 98 has a terrible time sleeping. It varies a lot but some nights she wakes around 2am and can't sleep again so she is exhausted the next day. And obviously there are longer term effects on her overall health.
She lives independently and is in reasonably good health- fully mobile etc. My sister visits her most days (I'm too far away to do that.)
I have suggested she asks for sleeping tablets if she has little sleep for days on end but she's not keen. I know they can have side effects.
Does anyone else have any experience of this?
