2 weeks to go!!!

 My biggest fear is, I have to go on this atkins diet to shrink my liver, and stay under 20 carbs a day, what happens I am staying under 20 carbs a day, ad the Dr. gets in their and my Liver hasn't shrunk enough, andhe can't do surgery, this really scares me, I have diabetes type 11, sleep apnea, arthritis in my knees, I am 6'6'' tall and 402 lbs, any advice for me or am I just working myself up for nothing? I would appreciate any input of any kind.... Thank you!!!! Jeff
