Hypoglycemic here, and my solution has been to mix whey protein 24g into my water bottle with a cytomax gel, the protein is vanilla, the gel, orange, ickkky, milky orange grossness.
but I have actually gotten used to it. I take a camel back for regular water, drink water for the first 20 miles, then alternate the mix and regular water camel back for the next 40, eat an apple or banana at about 30. Once I got used to the not so amazing taste of it all, it has worked well. Now I kind of even "like" it, or at least miss it when I don't have it along.
