When I got up this morning around 6 the dishwasher was still warm, so John must have finished loading it in the middle of the night, after sleeping in a chair for a while. He went to bed sometime after I got up. I got home from running and took a shower about 8:30 and he asked me what time it was. I thought he was getting up but when I went back to the bedroom an hour later he was asleep with a pillow over his eyes. I went to work then so I don't know when he got up.
In one sense it isn't a sleep problem because he isn't tired during the day. But he is sleeping later and later, which gets in the way of his being able to get things done. The exercise class he liked was at 10 am and I don't think he has gotten back.
The specialist said John shouldn't watch TV late at night because it would draw him away from sleeping. John said he doesn't have any other time to watch TV, since I don't like it on. The specialist said "Surely there is another solution for that."
I'm not sure whether to take the attitude that now he is retired he can follow any schedule he wants or to worry that increasingly disorganized sleep patterns will lead to problems.
