Is it bad if i keep doing this?

ok i have a habit of drinking something after i eat. and also i never drink anything b4 i leave skool. (well now skool's over now) but anyway i like never notice that i am thristy and sometimes my mom has to tell me to drink something. and sometimes i don't feel like drinking anything if i am reminded. so is this bad? if so wat can happen to me? and i think i no how this happened. my mom taught me if i finish my dinner i can have a drink (it's also the same thing with dessert) but i'm 15 and i no that. so anyway is this bad?

I'm 15 years old and I have the EXACT same problem. Just drink whenever your thirsty, but when you're sick, drink lots. I'm like you...I don't drink very much. But every time I'm sick and I don't drink a lot, I get dehydrated drastically and have to have an I.V. in the hospital. Other than when I'm sick, my body's been perfectly fine with not drinking water or whatever. You get lots of water from what you eat, also.
