Im going to offer my perspective. Group therapy sessions helped me initially. And occasionally I will jump into one. What really helped me was reading on this forum and a few others. And when I say reading, I mean reading. I have read about 900 threads going back years on here. Reading about other's interaction with alcohol and how they went about getting sober really helped me. I spend 30 minutes at a minimum reading others stories every day. On weekends when I have nothing to do I will spend several hours per day reading others posts.
This helped me especially in early recovery(the first few days) and then its helped me whenever I've felt like drinking.
