Greg you have had one helluva a year. I will follow along as you post your journey. I wish you the best in your recovery and your goals. When my dad was very sick with his pancreas he was on a low fat and low protein diet. It was tough for him as he generally eats in a paleo'ish plus ice cream style. It sounds like you have had a great supporting cast with your surgeon and doctors.
Best wishes with everything.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
