100lbs, that's awesome! Congrats. Keep training bro, my mate had the same problem, he done a mass cycle, filled it out and cut up, mass, cut, kept doing various cycles until it finally disappeared. Took him quite a few years but he eventually did it. Was left with stretch marks but alot better then a flap over the waist. If your after a quick fix, I'd have to agree with the others and a tummy tuck. I'm sure if you keep at it and not rush things, you'll work it off mate. Afterall, good things happen to those who wait... Success don't happen overnight.
