I took the 12 shots of Evenity, which ended in July of this year. I could not get surgery due to the Osteoporosis. Finally, my surgeon felt that my bones were as strong as they are going to get right now and will be doing my infusion surgery within the next two months. I still can't stand over four or five minutes since my injury. I had no heart problems when I had started Evenity. The only thing that I had noticed was waking up around 3:00 a.m. and it was hard to get back to sleep. I was tired the day that I got my shots. I hope this helps.
