I made a comment on another thread earlier- we learn a lot about what we are (and are not) like as people when we really and truly and permanently stop drinking. Some of my ideas and opinions about myself remained true as I'd known them but plenty have not.
I'd also throw in that rarely is anyone a special snowflake when it comes to needing to adjust who we think we are when drinking and who we can be in sobriety. There's a change for each of us. I believe it can only be for the better- if we get sober and work a program to live in recovery, which is a big step beyond just not drinking. That's the life I have found.
