Welcome back. What meetings are you going to? Sounds like you need to be going to NA meets. then keep going every day for 90 days, get loads of phone numbers and make a habit of aclling three members every day so that when you feel like using, its automatic to call a member, find a sponsor and ask (ask = ass saving kit) them to help you through the steps. DOn't be shy your life and your sanity is at stake.
Read the basic text, read at least a chapter every day. I am happy to talk to you Priavtely if you want help.
