: Good question
I think relapses come when, for various reasons,it becomes too hard to do the work necessary. or to keep the keen awareness..
Then some have have slid back.We eventually begin again, this time more knowledgeably and usually at the step that took the most work.
For me it was step three.
I am glad you are aware that it could happen.That in itself is valuable.So make it fun and easy and you too will have a success story.
