I wont post 12 step stuff as you asked not to, let me share this with you though...
A good friend of mine had a similar experience, his after 18 months, had a couple thought the same as you and told everyone so...so another 4 months pass and at xmas had 2 NA beers with his brothers saying he didn't like the taste but didn't want his brothers to feel awkward...then another few months and back to drinking, then rehab, then back to drinking...
Thats the only one i know with a similar experience, doesn't have to be that way for you though...hes a good friend and i hope he finds his way!
