I went to my first CR meeting in '05, I had a week sober and it was a large group of men, very welcoming and supportive. The problem was me, I had a hard time saying that Jesus was my Higher Power because at that time He wasn't. I stuck around for a month but after that I sought AA for my recovery.
After 5 years of sobriety I went back to CR for about 6 years, I was lacking something in my recovery program and I knew that faith and beliefs was what I needed. This time I got a sponsor, went through the workbooks with a group, and got active in service. I still attend the same church, and although I'm not currently active in CR I think it's a wonderful program if you can find a large group that keeps it lively.
