1. Read SR every day. You can learn much from the postings of others.
2. I gave myself permission to drink sweet non-alcoholic drinks (lemonade was my favorite) and to eat cookies as needed when trying to kick the initial sugar cravings and break established drinking routines. Yes, I gained weight, but now I'm into six months of sobriety, no longer crave sugar like I did in the early months, and am now losing the weight.
3. As cliched as it sounds, really take it "one day at a time"... Swear to goodness, this helps.
Good luck to you...
