Hey,
I don't think hope is lost if you don't get it on the first few tries. It took my four years and many tries from the time I knew I had a very serious problem to the time I took my last drink.
In my experience, whenever I tried during those four years to stop drinking I had this idea, way shoved in the back of my brain that someday, somewhere, somehow I would drink alcohol again. Not in the scared way, but in the sorta hopeful way.
When I banished this idea and was okay with it, the forced sobriety turned into just being a non-drinker. No way. No how. No alcohol.
