Hey Blacdimin,
Yes there usually is excess skin, depending on the elestically of your skin. And alot of that depends on your age. But excess skin is much better than fat. The excess skin can be covered with your clothes. Also after you reach your goal and stay there, some insurances cover skin removal in certain areas. Alot of it depends also on exercise and how tone your skin is to begin with.
I had surgery in Oct 2006, so I'm 9 months after surgery, I've lost 64 pounds and trying to get to my goal of 160. I am 5' 9".
Even with the excess skin, I would still do it all over again because excess skin is better that fat!!
Good luck
