Hi,
I'm sorry I can't offer you any advice, as I'm not quite at that point yet, but I did want to say welcome to the boards. It's a great place for information. I hope your surgery went smoothly and you are recovering well. I know it's easier said than done, and I'll probably be in your position in a couple of weeks, but try to relax and focus on drinking, drinking, drinking. My nutritionist told us not to stress too much if we didn't meet all requirements in those first 2-3 weeks. Just do the best we can and get in as much as possible. I hope things get better for you soon. Good luck. Keep us posted.
