Hi Blondebomber
Just wanted to bump your post up to the top, as you haven't had any replies.
My Mum (age almost 99) falls asleep all the time, in fact when I visit her in the care home the majority of the residents are fast asleep in their chairs. There are a few who need help with eating and even that is a "work of art" by the carers trying to spoon feed the sleepy ones
Perhaps it's due to the medication he is on?
I hope some others come along and reply soon
