good luck no name. Try to relax and get some sleep. Eat healthy and 'know' you'll be fine. Like the great Stewie Griffin said, "Whether you think you can or can't, you're right." Quick and healthy recovery to you.
Not taking care of yourself is selfishly depriving those who love you of time with you. Stop being selfish. Your friends, family and loved ones deserve nothing less as do your colleagues here on the boards.
Hope your surgery goes well and you make a full recovery. I recently had a scare with my kidneys. Fortunately, so far, changes in diet should be enough to take care of it. Take care of yourself man! All that stuff about the negative effects of too much caffeine, alcohol, salt, sugar and protein is for real. Best of luck to you!!!
PS - You can be in great shape and truly healthy at the same time. You just have to learn how.
