Upset stomach?

[OakLeaf]

A full stomach stimulates emptying. So it might depend on whether the distress is in the upper or lower GI. You'll stay better hydrated if you gulp, and have less stomach sloshing, but it's possible it might cause more lower GI issues?

Thanks for these suggestions thus far. I may need to reconsider the apple on my car ride home from work if I'm running that night. My goal is 10 miles by the spring, so I better start experimenting now to make my life less miserable as the miles increase.

Thanks!
