@jozer I was on alendronate (brand name Fosamax) for 18 months for the same reason you were - doctor prescribed it without discussion and I did not know anything about osteoporosis medications.

But then I got educated and a new doctor was happy to take me off of alendronate and put me on HRT instead. I waited 6 months into the HRT and then did self-pay Bone Turnover Markers tests. Although both my CTX and P1NP are quite low my ratio looks quite good. At my slow bone building rate it may take more than 2 years before DEXA shows a change.

If you are happy with the path that you are on now with Reclast (zoledronic acid), and there are good reasons to be happy with it, then great! But you may not be locked onto that path.
