I never went back for my 4th injections. I suffered for insomnia from the start. When my heart palpitations got much worse, I tried to get in touch with my endocrinologist, he did not return my calls. By the time my condition had worsened to the point I had the wear a heart monitor for 72 hours, he finally returned my call, only to tell me no one else in clinical trials had experienced these side effects. Just from reading the hand out I received at his office months before, I knew he wasn't telling me the truth. I'm finished with Evenity and him. I lost all my confidence.
