Any moms of multiples out there??-belly woes!!!

I am a 41 yr old mom of triplets and I gained tons of weight while pregnant (carried to 35 weeks). This was 8 years ago!! And my stomach and sides are just so jiggly and I can't seem to get rid of it!! I don't have lots to lose and it is mostly wrapped all around my middle!!! Ugh- will it ever go away?? I find it disgusting- not to mention the stretch marks!!!
