After one injection my side effects have been horrible. It has been 3.5 weeks since the injection and I am still feeling the side effects. The worst two are the occasional chest pains and the daily lightheadedness. The fatigue is finally slowing itself down and the muscle cramping is not as bad as it was. The flu like symptoms are subsiding as well. It has also affected my A1c in the wrong direction. I refused to take another dose. I have been told that it can take up to 3-4 months for the effects to go away. I am not enjoying this at all.
