Dad used to doze off all the time.

During 2006 and 2007 Dad used to fall asleep a lot. He would just doze off. In the car (passenger) at home in front of the TV. When Mum was in hospital he could doze off at the most inappropriate times. For example when Mum was being resuscitated and intubated, when Dr's were discussing Mum's treatment. I think it was Lewy combined with stress. After Mum passed away Dad had quite a few episodes of narcolepsy. He would be drinking a cup of tea and just nod off, dropping the cup. Or eating and just fall asleep, head first onto the plate. During this time, he also when napping, would reach out his arm, plucking at the air or bend down trying to pick something up off the ground. This happened a lot during 2006 (Mum had bad rheumatoid arthritis) and late 2006-2007 (Mum was in hospital, COPD). Now Dad doesn't nod off much. He went from dozing perhaps up to 10 times a day to now having an afternoon nap every third day. And the plucking motions don't happen much now.
I have noticed over the past year, if I alleviate things which stress Dad out he has much better days and nights. I will over time discuss these things.
