I came here to BECAUSE I wanted to quit. I took the name "Firstymer" because it was my first serious attempt to quit. That was 2 1/2 years ago. I haven't had a drink since the day I arrived here. I consider that, in large part, a testament to the help and support that I received from you kind people.
So, yes, it can be done on the first try. Please don't think that you are destined to fail just because this is may be your first serious attempt to quit. Life does sometimes give us second chances. But not always.
