Very, very helpful information. Thank you. I ordered the recommended book, and it should be arriving today. I'll also check out those videos. I inquired about Tymlos which my Dr. also mentioned. I would go in monthly for 6 months. He said afterwards I would need to go on another medication as if that isn't the case with Prolia. Sure hoping I get some clarification with reading the book and watching the videos. If only I could take my Dr.'s recommendation and go with that. Thanks again.
