Hi Aspieman,
Going to a mindfulness class sounds a great idea to me. Mindfulness and AVRT both really helped me.
A definition of mindfulness I like is Jon-Kabat-Zinn's "Mindfulness is paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally. And, I sometimes like to add, as if your life depends on it."
When applied specifically to cravings, mindfulness is sometimes called urge-surfing. Here's a link to a guided urge-surfing session by Sarah Bowan that I really like. It's only about 8 mins long:

I would be interested to hear how you got on if you do go, or on your views about the audio. No pressure there then!
