I agree that it can be a commitment in yourself to never do it again. That's how I quit smoking weed and cocaine and tobacco. I didn't go to meetings or have any support. I was properly hooked on all three. With cocaine to the point that my ex and I weren't paying out bills and getting high instead..... it went on for years!
I used AVRT with all three I just didn't know it. Anytime I thought about doing it I told myself NO..... You don't do that anymore. Today I never even think about doing a line of coke or smoking a joint. Never.
I can do it again with alcohol.
