Hi everyone. Thanks for letting me join, it's just sad that we all have one awful thing in common. 
my mum was diagnosed last august with lung cancer, which has spread to her brain. She has two tumours. Unfortunately she also has dementia. She's only 76, no age at all. My question is, is it normal for mum to sleep so much? The last couple of weeks she has been sleeping more and more. In fact, while sitting outside in the sun, she fell asleep. It just seems when she sits or lies down, she drifts off. I just wondered if this was normal xx
