mangoes, you can (should) switch to an anabolic. It sound like you were on Reclast for two years and have been on a drug holiday for two years. If so, the timing is perfect for starting an anabolic. Evenity, Forteo and Tymlos bone building effects would be delayed but with Forteo at two years, you'll have have equal bone bmd addition to those who haven't started with bisphosphonates.
The reason you want to switch is that Reclast restricts bone remodeling. The best bone is remodeled bone. Reclast stops fissured bone from breaking down. In doing so it stops new bone from being laid down. You aren't refreshing your bone on Reclast. The reason they don't advise staying on Reclast forever is because the bone you are saving becomes avascular and brittle. And you'll be glad to get away from those side effects. I think Forteo is the best choice, but I'm highly prejudiced because it is the only osteoporosis drug I've taken.
