Like Ivona, I drank a lot of lightly flavored carbonated water, especially the lemon/lime and cherry varieties. For some reason I also particularly liked the Whole Foods brand of black cherry soda, which is more of a conventional soft drink with lots of sugar. But mostly, I just forced myself to drink lots of warm water.
I'm not actually sure how much short-term hydration affects neuropathy, but I do know that it's supposed to have a significant effect on the likelihood of kidney problems. If the chemo drugs spend more time than necessary in the kidneys, where they normally aren't needed, they can damage the nephrons and reduce kidney function. So even if it doesn't taste good, keep drinking those fluids!
