Some days will be easy and you'll wake up and realize that you didn't want to drink the day before and you'll be happy. And other days you'll have a trigger moment (wanting a glass of wine while cooking dinner, going out for pizza, hard day at work, whatever) and you'll struggle. Stick with it. Be strong. Reach out to others who are on the same path.
It isn't easy. But few things that are worthwhile are.
