Major Fart! (finally)
Greg, I can understand the frustration you have, as I've been through it. Let me assure you, if you are following the advice of your surgeon/nutritionist, and you still aren't losing weight, you are just in a stall, and you'll eventually begin losing weight again. Your body has control over when you lose, and sometimes it puts a hold on the process. Besides, if you are working out, you could be gaining muscle, which will increase your metabolism in the long run, and in the short run make it appear like you aren't losing anything.
I'm going to have my wife take a picture of me and update my avatar today. I've been waiting until I reach the 100 lb mark before I updated it.
