I was just diagnosed in January and was put on this med. It is the least invasive to the body (except eyes which my doc said is a very slim chance that would happen) So far a few months in I have been doing okay BUT I have changed my diet and lost weight too so not sure which is helping more. I did experience some stomach issues and it made a little dizzy and tired. I have to stay active and eat a clean organic diet along with meds. My diet has helped with fatigue! Hopefully it will keep me going for a long time. Good to see you are supporting your wife as it will help her. You're in this together...
