okay, thanks for these ideas. He usually does snack in the evening - after dinner. But I'm talking about waking up after going to bed and getting a snack. I'm going to check into some of these ideas.
I eat LCHF, ut I make a carb for the rest of the family. I think he's getting enough fats to keep satiated. It could be stress, but he's been under much more stress in the past and wasn't snacking then (not sleeping well yes- but not snacking too).
