My father is 74 and has type 2 diabetes. He wakes very early (4-5am) but doesn t feel hungry until around 10 when he eats. His lunch is typically at around 12-1 and his dinner is at around 6. I have noticed in recent weeks that he is teetering and slurring his speech quite consistently in the early afternoon between 4-5.....it concerns me that his eating schedule is the cause. He s on regular meds and sees his endocrinologist regularly but I am doubtful that he is truthful about how he is feeling and wonder if he notices the difference as much as I do. He is also more irritable than he used to be. Please advise on possible reasons and or actions to help resolve this
