Man, what a bummer! I'm so sorry to hear about this. As someone else mentioned, you should have been on a very low carb, high Protein diet prior to surgery. Did you stick to the diet if recommended? My doctor mentioned that he had patients before who did not do the diet and he was unable to operate as well. If you give it another shot, and I think you should, I would ask the doctor about the pre-op diet. I wish you all the best!
