Wow. I would be very leery about meeting him if he said step 4. It makes me think he is still not thinking clearly, or working with a sponsor. If he said step 9... I don't know. I'm probably being judgmental here, but I doubt that he could really get there after just 4 months off all those chemicals. Of course, my AH thought he was thinking clearly after just three weeks. Quack!
Whatever you do, remember to place your own serenity as the highest priority.
Take care,
