I had RNY gastric bypass July 12, 2010 and have already lost 100lbs. I started out at a whopping 447lbs. It has changed my attitude and love for life. Before i felt totally worthless and so out of place all the time. Now i love the way i look and the way i feel about me! I still have another 100lbs to go to reach my Dr's goals for me, but i just love the fact that i am only going on 5 months post op and am half way there! Its the best thing i've ever done for me and that is priceless!
