In my experience, i was in for 30 days and from day 1 it was non stop.
I was given, along with everyone else, a schedule that went morning meditation at 6am until lights out at 1100. I was busy all day. Very little recreational time towards the end of stay.
We had books we to read, homework we had to study that our counselors assigned to us based on our addiction etc. Etc.etc .
So if she had detox first, that should have been all encompassing. Detox isn't easy.
