plastic surgery for loose skin?

Now that I have been approved for surgery and am scheduled, I have started to think more about the after effects.  I know many of the older people have a lot of skin removed, but because we are younger will it be more likely to bounce back?  I have had 3 kids, so a tummy tuck will be needed regardless, how long after surgery do you contact a surgeon for this next step?

My doctor reccommends 6 months after you have been at a stable goal weight. For me that was 2 years after my original wls. do NOT DO IT TO EARLY! my friend who had hers a year after we had wls-she had breast lifted and augmented- continued to have her skin stretch and it has been a horror story.
