Mommy makeover surgery - anyone?

Hi all, I'm a mother of 2. Elder one is 5 years old and younger one is 3 years old. I gained a hundred pounds during pregnancy and delivered via c-section. I have lost all my baby weight, but I still look pregnant and my tiny boobs got to be huge because of breast feeding for a year. And I have a plan to undergo a mommy-makeover in a clinic in Mississauga as many of my friends said it will be a nice choice. But I'm really very nervous. What all are the questions I should ask my surgeon before preparing for the surgery?
