You drink 8 oz. of water daily? Is that a typo, or are you serious? That's not enough! You're supposed to drink half your bodyweight in ounces. I weigh 140lb, so i drink 70 oz. water daily (140lb/2=70 oz). If your urine is dark yellow, and smells bad - you need more water. If your urine is light yellow, you're getting enough water. Sometimes my urine almost looks like water, that means i'm getting plenty of water. But, in the morning when you wake up it might be dark, because you haven't drank for hours (while sleeping). So look for the color after your first one.
