I totally understand where you are coming from. How to keep up the momentum and stay stopped. I think this is part of everyone's story in a way. I don't know how many times I would stop, feel really great only to pick up again. I am now 20 months sober. What did I do differently this time? Joined and followed a program, listened to material on alcoholism and especially ways to avoid relapsing early in sobriety. That was my biggest worry, I didn't want to get on that merry go round again.
All the best CaiHong
