This is an interesting topic. A group of us were having a discussion about something similar to this after our NA meeting last night about when she left her program and they were saying to attend meetings every day for 90 days. The program is to teach us how to live the life we haven't lived. How are we to learn to live if we become slave to a meeting. I say if he can work with his sponsor to find a way that works for him. maybe a meeting 3 times a week maybe four could be good. I haven't done rehab I had to stick it out could turkey when i decided to get clean, but now that I have decided to go to meetings, I may feel i need them everyday and the days I want them everyday I will go. The days I don't I'll stick to my program of three times a week. He can't force himself to hard in my opinion cause that might force him right back to what got him where he is.
