@ymv If nausea and headache are too bad, go down one click. For a week or two. I almost never took the full dose and still got good gains. But of course it is optimal to take the full dose and it sounds like you will be able to without significant side effects. You do have the option of reducing and then ramping back up!

My doc does not prescribe Prolia and I have never taken it and never will. That means Reclast at some point anyway!
