First thing I'd say is everyone IS different! The poo thing's old blood and could take a while to clear but if you're really concerned, then seek advice. The wind could well be from the gas pumped into your abdomen so the surgeon can check for leaks. Your breath could be the result of basically "starvation mode" as your body's breaking down its fat reserves to use as energy. The pain from your port sites should subside, just watch out for the upper left one! It's usually the biggest and the one that's been wiggled about with the most.
I know this sounds crazy, but moving about may actually help - especially with the wind. Gravity and all that!
You're only a few days out and it's a VERY scary time indeed - you don't really know what to expect and what's ok and what's not! Concentrate on keeping to your diet sheet and taking your meds (says she stuffing her face with Lansoprazole..) These things should all settle eventually - can't give you a time frame though! Must stress again, though, if you're really worried seek medical advice. Maybe write it all down, give them a ring, and tick them off one by one.
