I know it's strange, but the only way I can really turn off the circle of addiction is praying asking for serious help (moment of despair), going on a weekly spiritual treatment (kind of exorcism, they call it "disobsession"), and getting rid of stupid friendships (social isolation).
This way in only a few weeks I feel very different, very comitted with being sober (it becomes a natural way of thinking), and I remember I'm not here to destroy myself and throw life away, but to improve myself. Sobriety is improvement.
It's an intimate question and involves faith and belief, only told you about it because you mentioned meditation. But even if you don't believe any of this, meditation can help diminish anxiety and therefore help with the urges.
