Congrats on the sober time. I think I would keep going,especially since you say your wife also thinks so. I have given a lot of serious thought to it myself. I sure won't deny I have "issues"
I know a guy that never drank that went to one also. I think he went for a year or so. He said it helped him immensely.
Maybe instead of going every week you could cut down,to every other week. And on down the road once a month?
I know what you mean about no turning back. But then again I always stay on guard. Right now I don't think I will ever drink again. But we often see people on here sober for years that started again. I always keep in mind I am only one drink away from going back to hell,and try not to get complacent.
