I seem to be sensitive to sugar also. I never drink Gatorade anymore and that has been a great help. I have used the Clif Bloks the last two years and like them.

This year I am also liking Hammer Gel or Heed. I have been using the flask so I just take a little bit at a time with water. I feel better during and after the ride using these products vs Gatorade/Powerbar etc. I think I am also consuming fewer calories as well because (I think) my bloodsugar levels are not spiking as much. At least that is what it feels like to me.

These products do contain fructose though, but here is some info.
