I am amazed how just sitting and breathing for 10 minutes a day makes such a massive difference! A couple of threads on here you might be interested in:

I also do yoga. Started doing them both earlier this year, I feel like they helped me get into the frame of mind to quit drinking.
Yes Carr does a book about alcohol too. I read This Naked Mind which I believe is a similar principle, helps you reframe the way you think about alcohol.
Started smoking when I was 14, stopped at 28, started and stopped/switched between smoking and vaping over the last couple of years (am 30 now). Stopped smoking in September, been nicotine free (i.e. off the patches) for 3 weeks
