While I don't teach mindfulness myself but my close colleagues do and it is very effective at managing problem thoughts (which include thoughts of engaging in addictive behaviour).
Stick with it. As you you practice you get better at it and it's more effective. As an aside it appears that not only can you build willpower by exercising it, it also generalises. So if you exercise willpower to not eat sweets you are also building willpower resist other impulses.
Keep up the good work, mate!
