#WIP Idea to Follow Up On -- aquatic panacea

i hit a bottle of water like an aquataholic hyperchondriac, any ill mood or sign of ailment is immediately countered with at least 8oz (usually a full 20oz dose) of the clear stuff. Aren't the benefits a little iffy, data-wise? is it because we're mostly water that it feels so good, or am i moderately dehydrated most of the time. is the typical american diet prone to this? any evidence exploring the link between hydration and performance out there? make it like a mini-research paper, with multiple sources and an actual essay-style outline. sounds fun.
