Don't be afraid. Most people take the meds and do fine. There's a selection bias online where you are more likely to hear about bad side effects; the people doing fine don't generally get on the Forum to say so. The key is having a doctor who understands these meds, and knows how to follow one med with another. You have lots of company here, don't worry. We have several Tymlos and Evenity veterans. Start a new thread if you have specific questions.
