Me too. I have been doing it for four months now and I swear to you my back has gotten so much better.
I have an appointment with a doctor next week to make new scans of my back.
I will make another post with the results.
I got the last scan just prior to sleeping on the floor and I wanted to start sleeping on the floor because I thought it would help me build up back muscles.
I think I have been successful in this undertaking.
So, if you follow me you'll be able to see the new post that I will make in about a week with the results.
Including pictures from my Doctor and everything (she mails them to me via mail).
