It is not his medications. He sometimes falls asleep while eating. He sleeps 12 hours at night and then gets up, and dresses and naps all day. Doesn't have much appetite, which is understandable He plays with his food, napkins and takes about 3 hours to eat, which is why he falls asleep while eating.
I hate to push him to eat, as he says, " What is the rush", and it only aggregates him.
