Has anybody tried bisphosphonates to treat osteoporosis?

Not the best. Bisphosphonates can reduce fracture and raise you dexa scan scores but they donot build bone. If you are osteoporotic and have already had a fracture, consider Forteo to build bone first.
Yes. As a rheumatologist, I use these drugs multiple times a day. They can be extremely helpful for osteoporosis and most are well tolerated.
