I am considering a mommy makeover. Can I have this done while awake?

There is no benefit to having such an extensive procedure while you are awake.  In fact, it would be more dangerous and less controlled.  The anesthesiologist is there to protect your airway and monitor your vital signs, and titrate the anesthesia to just the right level allow the surgeon to concentrate on the procedure.  

Some procedures are probably better performed under general anesthesia.  I
would search for the board certified plastic surgeon who you feel is
most likely to give you the best results and who performs hundreds of
these procedures each year. I would look at patient reviews as well as
before and after photos on that surgeon's website.Kenneth Hughes, MDLos Angeles, CA

Some procedures, like liposuction, can be done safely under local anesthesia and oral sedation.  Other procedures, like breast augmentation, may require more sedation. A full tummy tuck may require general anesthesia so that the muscles can be tightened while they are relaxed. I would suggest meeting with a board certified plastic surgeon and discuss all your concerns.
