That's interesting that you say that Jordan. I've always heard about the 8 glasses rule and felt I was miserably failing in that aspect of taking care of my health. I tend to sip water, more recently a bottle of sparkling water (without sugar or caffeine), throughout the day. I barely finish a 20 FL oz bottle per day, if I even finish that. So I guess I probably average about 2 drinking glasses of water during the day. I've wondered if some people just require less water than others, because I also barely sweat no matter how hot I get, and how much I drink. The times I've worked at it and forced myself to drink more than I want, I find myself visiting the restroom every 5-10 minutes for awhile until it's out of my system . I wonder if some people just physically require less water than others.

I suppose it's mentionable that I often wake up during the night thirsty and I keep a bottle of water by my bed. I suppose I may sometimes drink an extra glass during the night if I wake up.

Also it's true that you can actually "overdose" on too much water/fluids if you go to an extreme. It's called hyponatremia, and it's when you take in so much fluid you dilute the salt level in the body too far. It's actually more common than you might think, I have typed several medical records dealing with it before in my transcription, but it seems to most often occur in athletes who overdo it in trying to keep hydrated during sporting events.
