I relate! I first tried AA a couple years ago and I always left feeling depressed, isolated, and craving big time because of the first two things. But this time around I was in a program that made me do AA, and I got to see that there are specific meetings that make me want to give up... and others that give me strength.
I'm also at 54 days and I've been having a rough go of it since Wed. Tonight I had my first real legit craving since quitting. Seems like it's fairly common to have a tough stretch around the 60 day mark. Great job staying strong!
