When I quit drinking, I began living more honestly than I ever had in my life.. and it it such a freedom.
Sit down with them NOW, you have time to show them that you're 'better' now..
or.. if you really feel it would be best that you not drink at your wedding, but you're just worried someone will say something, you might just mention to them that you haven't actually been following the AA program, you feel you have learned to moderate and have had a glass of wine a few times since '07 as an FYI.
If you truly don't have an issue, it shouldn't be an issue.
Congrats, I hope it goes beautifully!
