This is a big deal. Will be praying for you, anon. Only advice is, find AA group if possible. If not, pray a ton for strength to keep at it, even when you are suffering. Serenity prayer can be said by anyone.
Sugar might be helpful. Probs. what your body is craving atm. Seeing sunrise and sunset always good for the mind.
