Yes, a battle. One thing that has helped a lot was my Dr. suggesting not going over 2 hours without eating something. When I plan these mini snacks, most times I’m able to say “okay self, it’s just head hunger. You had something an hour ago and will again in an hour, so hold tight and get over yourself”.
Doesn’t work 100%, but hey, I’ll take 60% help and trust that this muscle memory will get stronger each time I refuse to give in. Good luck!
