If you get this done (when exercise and diet won't hack it), get it done right. I got it done right with Dr. Spring. After completing LA marathon and eating right, still had people asking me if I was pregnant (no - "thanks" for asking). UCLA dx'ed me with diastasis (separation in ab muscles)/insurance won't cover (don't get me started)/quoted me $5,500 just to repair (would not deal with excess skin after procedure). I started researching plastic surgeons.
Scared of procedure? I'm a working mom of a 6 & 5 yr old. We sacrificed our body and lives for the next 50+ yrs in pregnancy, childbirth, and in raising kids. This isn't scary compared to that. Glad I did it and did it right. Beats being on Spanx catalogue mailing list (been there, done that).
