Also, when in doubt, drink a glass of water as quickly as you can for your particular stage of healing! Then wait 20 minutes. Often thirst masquerades itself as hunger.
So hydrate, hydrate, hydrate.
And even now, I have hungry, hungry, heifer days. They are tough to get through, but I make sure my carbs are low, protein adequate and that I'm staying in my caloric goal for the day and I drink lots of water, and exercise (walk) and deep breathe when those times come. It helps.
Welcome!
