Sounds like he is doing good. The docs have told him it takes 3 weeks for anyone on any kind of eating change to allow 3 weeks to not feel starved.
It gets easier as you go along. I can about count what he can and can't eat in my head. I eat the same thing, so that makes it easier also.
Something we have learned as we go along is to for him to eat an early evening meal, then Dessert by 7:30. If he wants something before bed, he will eat some peanut butter or a few crackers.
We also have learned that lots of things cause blood sugar to go up; mostly emotional upsets. As long as we just go along about the same, his b.sugar stays the same.
