I think the following how much water to drink chart may help you to SAFELY determine how much water you need to stay properly hydrated for your activity without over consumption.

Recommended Water Intake:
Step 1 Select an appropriate need factor.
0.5 — Sedentary no sports or training
0.6 — Jogger or light fitness training
0.7 — Sports participation or moderate training 3 times a week
0.8 — Moderate daily weight training or aerobic training
0.9 — Heavy weight training daily
1.0 — Heavy weight training daily plus sports training or “2-a-day” training
Step 2 Multiply weight (in pounds) by the appropriate need factor to arrive at the recommended water intake in ounces per day.
Example 1 120 pounds x 0.6 = 72 ounces per day
Example 2 200 pounds x 0.7 =140 ounces per day
We recommend that you drink water eight to twelve times per day.
Example 1 72 ounces per day divided by 10 glasses = 7.2 ounces per glass
Example 2 140 ounces per day divided by 12 glasses = 11.7 ounces per glass

Here’s Lewis Black with a little humor on the subject of how crazy water consumption is today.
