I have the same issue, numbers within range all day and bedtime but morning one is terrible, I have got to the stage of not getting stressed about it, so you are not alone with this one
A few years ago i suffered with sleep walking/eating. Id wake up in the early hrs stood infront the chocky cupboard with loads of empty wrappers on the side. We tried everything to make me stop but nothing worked untill i had the idea to swap the medical cupboard with the chocky cupboard because we could lock that one and my mrs keep the key.. that worked yippee!..
...untill last night!.
...we got up this morning and realised my eldest had came home last night and left a full box of celebrations on the side - which is now a empty box!. I ate the bloody lot!.
