What are the key statistics behind Michelle Palmer's 31-month recovery milestone?

The available content I have only goes up to my 22–23 months clean milestones, where I celebrate that recovery is possible and track my progress from active addiction to over a year clean and then into the 20+ month range. I do not have verified public stats for a 31‑month milestone in the retrieved content.

Are you looking for:

1. A timeline of my recovery (months clean and major milestones)?
2. Or general relapse/recovery statistics for people around the 2–3 year mark?
