Okay so everytime I do a race or sometimes after a strenuous workout, I feel nauseous. Some days are better than others, but it's still there. It was really bad after the Splash N Dash I did last month and has me hesitant to do another race for a while.

So what can I do to avoid that?

FWIW, I'm still new to the energy shot bloks and gu's and my general eating habits include more junk that it probably should.
