Hi Gremlin,
Welcome and I am glad to hear that you are making a decision to take care of yourself.
I think there are drugs to help with cravings, but I don't have any personal knowledge of how well they work. I am not an AA person but I am sure others will be along who can advise you on that. What I would say is that it takes work every day - physically, mentally and spiritually, to stay sober.
