My two cents is that you gotta eat. The blood sugar thing might be impacting your cravings. Plus, you’re probably malnourished from the years of alcohol abuse. So, eat when you’re hungry, but try to make it good stuff. And when your cravings are the worst, try grabbing a piece of fruit or having a balanced meal. It really helps me. I often confuse wanting to drink with being hungry because I drank through my hunger for so long.
