From what I'm reading here, I may need to back off on the Cytomax and hit the NUUN harder. Do you think I need to put more plain water in there too or the electrolytes without the sugar are OK?
This is what I found most interesting about the article. It's not necessarily the sugars. I avoid sugars in my fluids too but use electrolytes heavily because I am a very salty sweater. So it turns out that the potassium etc can shut the stomach down too if it's in too high a concentration. So what I'm taking from this is that I need to water down my electrolyte drink more, make sure I take in some plain water with my endurolytes and watch my effort level in the early stages of the ride. Sounds like a similar thing for you. I used to use Cytomax but after a while it started giving me lower intestinal problems.
