Graves Disease and Learning to Be Fit

I'm jumping on the bandwagon; I see so many people on tumblr that have totally transformed their bodies and I'm inspired. I have spent that last several years yo-yo-ing in part due to Grave's Disease and not having a thyroid. But why should that stop me from wanting to be in good health and great shape? I will beat my body through this!

HW: 220lbs (~2/12) CW: 198 (5/13/12) 1st GW: 160lbs (6/30/12) That means just over half a pound a day! I'm also using fitday.com to track my food, exercise and mood.
