not falling off the wagon

I have noticed that some people have commented on the forum and in the step groups that they have returned to RR after being away for some time. I'm wondering what happened, if you don't mind sharing. I'm on step 3 right now, and I'm concerned about getting to the end and relapsing. I want to know if there's anything that can be done to prevent it. What can you do to stick with this program and not have to come back to it after a period of being re-enslaved to the sugar drug?
