Sorry to hear it. Here's a few (disorganized) thoughts that hopefully will help somewhat:
1. Be very careful with the FOSAMAX. I had a close relative who actually developed a duodenal ulcer - not esphogeal - from the stuff (we are pretty sure). She was very, very, very sick from it. It has been reported enough to where they have studied the issue:http://www.ncbi.nlm.nih.gov/pubmed/11966346
2. I can tell you which kind of calcium to be very cautious about: coral. This has a history of lead and mercury contamination and, although some manufacturers claim to be stellar, I can't see any compelling reason to risk it.
3. As you probably know, Vitamin D, magnesium, exercise and boron are critical to bone maintenance and, arguably, just as important.
4. Have you had your testosterone checked? If your testosterone gets low enough, it's possible for your estrogen to follow and dip low enough to lead to bone loss (even in men).
