Gravity 3, Prolia has a bad history because it wasn't known that you can't be late for or miss a dose. It wasn't known that you have to follow Prolia with another pharmaceutical. The destruction that followed was devastating. You might be safe with Prolia, now. Prolia is terrifying to me. Some report good results. If my endocrinologist wanted me to follow with Prolia, s/he'd never see me again.
In your situation, I'd take another round of Forteo.
I'd trust windyshores more than I'd trust gently.
I'm curious about why you are stopping Evenity after three month. That seems wise to me.
