I also have gained weight. I was overweight to begin with. I feeling very well with taking synthroid and my TSH is 1.58 ( supposedly normal ). I have energy and I sleep very well. I am starting an exercise program for myself and a weigh and measure of food. I have just started so I have no results yet. I would very much like to correspond on my email. I work for a university. My Graves was discovered by accident last November 1995. I had RAI in January of 1996, hypothyroid by April and I had a HELL of a summer. I was very sick, I not only had the Graves to battle – I had Lymes Disease besides ( that is an illness caused by a tick). Everything started turning around about September 1996. My only problem is the weight. Graves Disease is hereditary in my family ( my father’s side ).
