What to expect in radical sanation process?

I married my husband in a civil wedding last October, only a few months after I’d started going back to church and exploring my Catholic faith again. My husband was raised Catholic and has all of his sacraments, but he doesn’t practice and after some discussion, he decided he just isn’t comfortable being too involved in any Church processes, including the pre-Cana that would be normally required to be married in the church.

Because of this, my priest has offered to go through with the radical sanation process so I can start receiving the Sacraments again. Apparently it requires far less involvement from my husband. Has anyone else gone through this process? What can I expect? How long did it take? I’m finding it hard to find info on how it works exactly. I meet with my priest to talk more next week but I’m a planner and would love to know some stuff before.

Thx!
