It will be at least 6 months or more before I have another scan, and honestly, I'm not sure how long I'll be able to tolerate the side effects of the strontium. It's affecting my memory too. And the sinus headaches are becoming too much BUT I may just cut the dose in half. There is still a lot of evidence that doses even as low as 200 mg a day are effective. Right now I'm taking 680. We'll see. If I stay on it I will come back and post my scan results. In the meantime, take good care of yourself! We are on a terribly perrilous path! I am convinced that if pharmaceutical company R&D departments were filled with women over 60, osteoporosis would be cured by now! And the treatments wouldn't be torturous! Wishing you health and to feel much better soon!
