T.K.
I also had 2 c-sections, but I did not have any complications. For me, going into the 2nd one was a lot scarier. Just knowing what you're walking into, it's hard to stay calm.
One thing I did after both sections, was when I got home I wore a compression garment. They now sell many types of these. I just happend to have a pair of tight spandex "bike" shorts and I wore them constantly. They weren't too tight and they weren't uncomfortable, but having that compression againt my stomach helped.
Also, like a few other moms have said, be careful about what you lift. That is what is going to do the most damage.
Congrats and good luck!
