Thank you Windyshores... your comment may be correct, in which case I wish I had known this 8 months ago. Nevertheless, maintaining the gains of Evenity by using Forteo still might have advantages. First, maybe the forteo would continue to build bone. Second, unlike the biphosphonates which tend to freeze everything, the forteo would not freeze everything. That might allow a better chance of re-building bone through exercise programs such as weight lifting. You're right, I need to talk with a doc. But meanwhile other's experiences help me understand the possibilities. Thanks again.
