I was recently diagnosed with Celiac. I am from Trinidad and Tobago (Caribbean) and its not a very common disease here. I am tired all of the time. By 2pm I am ready to find a bed..anywhere! I am awaiting blood test results for thyroid functions, iron, calcium and a lot of other things that I cannot remember right now. I have also signed up with a nutritionist. After reading some of the comments, I think that I will start slowly to do some physical activity...maybe I will start by walking. I hope that helps.
