@gravity3 - Not sure I would use the word confident at this point, but willing to try this option. The reprieve from headaches, bone and muscle ache and lethargy from Evenity feels wonderful. Not sure I'm ready to swap those out for potential gird and muscle ache with Fosamax. Also, I will track the direction of bone turnover markers to make sure things are going in the right direction. I can always stop the SC mineral and take the Fosamax (while continuing Liftmor-type exercises, etc).
