Copperfield, I'm glad you keep trying. It's not what you do that makes a difference, it's what you bring from the inside to what you do. As long as you're still carrying the old you around, nothing will work. When you're ready to give up on all your old attitudes and really try to look at life and yourself with an attitude of accepting that you can't drink and willingness to change, anything can work.
The "I probably won't drink" attitude suggests that you think drinking is somehow out of your control -- you might or you might not, you can't predict it. But picking up the first drink is totally in your control. Are you committed to not picking up the first drink? If you are, then you never have to have a hangover, regrets, or remorse again.
