I didn't really know what bothered my stomach. It started around 42miles or so - fairly early on, and I didn't bring or buy anything I don't usually eat . I had a Payday bar and before that a handful of peanut butter pretzels, cashew and chocolate covered raisins. I had electrolytes in one watebottle , some shot blocks and the home made pan forte fruit-nut bars I bring all the time. Later on - I felt better and the wind was less of an issue. I definitely got a second wind on the way home, after the nice long downhill section.

I don't know that I would ever go for a longer brevet (300k or more) but the 200k distance is do-able and makes me feel like I've really accomplished something.
