Drink 1/2 your body weight of water in ounces, daily. Example 180 lb = 90 oz. of water daily. Divide that into 8 or 10 oz. glasses and that's how many glasses you will need to drink, daily. Use 1/4 tsp. of salt for every quart of water you drink. Use salt liberally with food. As long as you drink the water, you can use the salt. Avoid caffeinated or alcoholic drinks. These are diuretics and will dehydrate you. Every 6 oz. of caffeine or alcohol requires an additional 10 to 12 oz. of water to re-hydrate you.
