If you sat on a butt-o-meter and got a saddle 2 cm wider than your sits bones, then maybe the problem is too much padding? (depends on your soft tissue structure, and everyone is different) Width of the nose (either not wide enough or too wide)?
It does sound, too, like you might have too much anterior pelvic tilt going on. Your fitter should have told you how many times and in what time frame he can recheck your fit without additional charge. With the amount of distress you are describing, it certainly sounds like you need the fitter to help you tweak the fit some more. (hey, that $150-$200 you spent on the fit is an investment for more than just the 2 hour fit session!:D)
Edit to add: Oh, and the inevitable plug for the fabulous book: Andy Pruitt's Complete Medical Guide for Cyclists. Good book.
