Welcome, cbf!
I'm one of those who relapsed many times. I'm now nearing 14 months but have learned the hard way not to become complacent. For quite awhile I couldn't figure out why I kept relapsing. I finally went to my favorite pdoc and was brutally honest, then did a 3-month intensive outpatient program plus AA, later followed by meds fortification. I'm now off those. Best thing I ever did for myself!
On the ongoing saga of my adjustments to the retirement place: I now don't even bother going to the weekly cocktail party and skip the occasional wine and cheese party, too. I simply don't have any interest in that anymore. At dinner, only one or two people at my table now drink with dinner instead of all but me :-)
