i'm now working in a different buliding. same company. same job. but now we have free bottles of water. rumor has it they don't show up that often, but they arrived yesterday and i procured a bottle of glaceau smartwater. it tastes like water and it looks like water. the little pint bottles are cute and comfortable in my hand. the packaging is clean. but here's the thing - i'm drinking water with electrolytes! it's like gatorade without all the color and flavor. and it's freaking me out. where are those electrolytes hiding? why can't i see or taste them? i can't even feel them on the back of my tongue. my body is just absorbing them. and what if i start drinking five pints of "vapor distilled + electrolytes" enhanced water every day? can a person suffer from an electrolyte overdose? i think i'm about to find out.
