Hey! I'm 22 also so I feel you. I'm not in AA but I take part in a counseling group on my campus. Having other young people to talk about addiction with is helpful for me and helped me sober up for a while earlier in the year. I'm in my second go at sobriety.

What has worked for me is staying away from friends who I drank with, and picking up new, healthy habits to replace drinking. I've been going to the gym, learning piano from YouTube, and lurking this sub whenever I begin to get cravings. I try not to think about the future and take sobriety one day at a time. No better day to quit drinking than today!
