You can stop meds. First you have to go on a "relay" drug (if in my case I decided I wanted "off" Prolia) it would be Reclast or Aclasta as its called in Canada). After that, I could stop. The thing is, even when you stop taking bisphosphonates, I believe those drugs remain in your bone for years.
Osteoporosis is a disease which should be treated. If you have high blood pressure, you don't just stop taking meds.
And then there is the "F" word: Fractures. I fear fracturing. I already deal with limitations from osteoarthritis and most likely a hip replacement lies in the not too distant future. I have a n older husband with very serious health issues, no children and family in other cities. So, need to remain independent and not wheelchair bound for as long as possible. So will have to take my chances with these drugs (and I worry about these meds too). Always individual decisions when weighing risk vs benefit. Good luck to all of us.
