I've been through many surgeries where I feel pretty good for a few days afterward, and then all of a sudden I feel much worse one day. It definitely does happen, but I am still very sorry. Do listen to your doctor for sure, I know you really want to be as independent as you were before and keep your life as normal as possible, but you'll thank yourself for rest later. Just keep taking your pain pills and take it easy! You'll want your energy for after you get your new tits and they're all ready to be enjoyed!
