How to make myself drink more? (water... i'm dehydrated)?

first of all i'm kind of a water snob (like only aquafina and sparklett's) but either way i really don't like drinking a lot of water because like after 1-2 gles i feel almost sick and like my stomach is about to burst (which is weird because i can eat way more food and my stomach's fine with that), then i don't like tea cuz it's just too bland and i don't like those powders you add to drinks to make them taste better, anything else (gatorade, OJ, lemonade, etc) are just eh and also more fattening so i'll just deal with water but right now I go days without water, i figure i get enough liquids from food cuz i haven't dropped dead yet. im like a camel... ANYWAYS, its really bad for me and i want do drink more, any suggestions on what i can do
