That's awesome! So you're coming up 2 years soon? And yes you most certainly should be proud of yourself! That's a huge accomplishament!
But I know what you mean about the general population not being proud of it... for me, I don't go out of my way to tell people I used to be a drunk because, well, I'm ashamed of it, and it's quite frankly embarrassing. Instead, if that topic does come up (however extremely rare) I will frame it by saying how long I've been sober, not that I used to have a drinking problem. This puts a positive spin on it and makes me feel proud of myself rather than ashamed or embarrassed. I guess the tattoo idea is the same thing, but this way, maybe I can inspire others with my story (because people will always be asking me what it means) to make necessary changes in their lives, and hopefully make the world a little bit bette of a place.
So there are these things called "chips" that this little club gives out AwesomeKev. I suggest you look into it... I think most importantly you would help a lot of people, and that will help your sobriety in turn.
