Laser treatment then tummy tuck? (photo)

this is in addition to my original question about having laser treatments then having tummy tuck. my total weight gain with the twin pregnancy was about 30 lbs. I had gained 15 lbs with all the invitro procedures prior to actual pregnancy . I am posting pics now as well to hopefully give better idea of my situation. I really appreciate the doctors that have responded back. Dr. Wong did mention possibilty of high risk of diastasis after twin pregnancy.  Original: I am 4o yrs old non smoker no medications no stretch marks delivered twins naturally 8 yrs ago . I am also 40 pounds overweight at this time but the opportunity presented itself and really considering it although feeling so much anxiety and fear. I am a nurse myself but once you become a patient you feel like you know nothing . Any feedback would be greatly appreciated. Thanks very fearful of post op downtime . I'm Very active so have major concerns
