Sugar lunacy is pretty common the first few months. It helped me to have snacks around that weren’t sugar (almonds, pecans) or that at least had some nutritional value, like dried apricots. Hot cocoa was good too because it took longer to drink and with milk it at least had some protein.
Fiber, protein and lots of green leafies helped. I’m not sure what your limits might be with fiber with a gastric bypass...do you have a nutritionist that you saw post bypass that you could talk to?
One thing is for certain...quitting alcohol can only improve your health, especially if diabetes is a concern.
Congratulations on 51 days! It gets better, I promise.
