I do not think the Prozac would be doing it, but doctor's will prescribe Lamictal for individuals who are not bipolar as well. I could not function on it. I started out at 25 mg. the first week, up to 50 mg. the second week and told her I could not function on the Lamictal. I was so drugged feeling on it - she took me off. What mood disorder med did she give you? I have taken almost every med there is old/new and none of them have helped me. That is why I was sent to an endocrinologist and she found the enlarged thyroid. I hate to think of it being cancer since I have been sick for two years. I am a totally different person than I was. I was always full of energy, go, go, go, etc and now I can hardly get out of bed, had to quit my job (after 14 years), and can't drive. My husband and daughter take me to my appointments. I am 46 and have never in my life been sick or experienced anything like this.
