Welcome. Don't listen to that Rewire character - he's always full of shit.
Just kidding - of course.
When a crave hits, remember your promise. A crave lasts 3-5 minutes, then it's over. Grab some digits, and if the crave seems more than you want to handle, reach out to someone.
Post your promise every morning, and keep your word. It's simple, but hard as hell to do. But, every one of us has been through it. If we can, you can.
Proud to be quit with you.
