Just over 4 months sober and I understand what you are going through, be kind to yourself, treat yourself to whatever you want that is not alcohol. Think of yourself as an invalid or a small child that needs to be nutured, to grow and strengthen.
About the eating, I craved sugar now I am returning to normal. I wouldn't restrict myself, your fight is with alcohol, not food.
You gave up alcohol for a reason, remember that. Stay strong
All the best
