Me too, what are you eating that has all the fiber in it?
The only time I tracked that I ate that much was when i was experimenting with a carb load day which was heavy on oatmeal and multigrain bread. And I felt like I was going to rupture the next morning (just generally bloatey).
Like Brick said, drink a lot of water, and don't sweat it if you feel fine. Cavement who spent time eating leaves and shoots and whatever may have had fiber intakes many times higher than yours.
