Sounds a little familiar to my IM experience... but I had no nausea. Felt more like the flu - hot, a little dizzy, strange cold sweat, diarrhea, uncomfortable but not yet cramping. It did take me several days to feel like I could eat like a human again afterward - I did feel some bloating there. I sure am glad I stopped running and at least had the sense to stop consuming for a while. Next time I'll try just water to reset the system faster.

Makes sense... our bodies weren't exactly made to absorb so many liquid calories, especially sugar calories. I just can't stand to eat solid food while exercising, so I guess it's a matter of finding the perfect balance.
