Hi Meg
I know that when they are working a program, for some reason they need to be cheered on, on a regular basis. I think at first it is encouraging and they feel really good about quitting, but after a time the cheering stops and they realize that this is "FOREVER" and it scares them.
Now that doesn't mean you have to go out and buy pom poms, nor do you have to reward him with anything, but maybe you could "gently" suggest that this would be a good time for him to stick close to his sponsor, if he has one, and to do extra meetings.
They have to work through it, and a little encouragement goes a long way.
