If i am drinking 0.33liters of water per day then how much am i suppose to drink more?

Whatever satisfies your body's needs.

You should drink about 2 liters per day, I drink about a liter in water, just drink like 1 or 2 glasses while eating instead of juice or whatever, once your into water you'll enjoy it a lot xD

An adult male/female needs about 13, 8-oz. cups of water each day, while an adult man/woman requires about 9 cups each day. A safe, reasonable amount is to commit to drinking 64 oz. of fluids each day.

Remember that although plain water is the fluid of choice, food you eat provides you with fluid as well. Foods with a high water content include melons, citrus fruits, soups, leafy greens and ripe tomatoes.

Your body has multiple needs for water, such as removing toxins from your organs and moving nutrients from foods and beverages to your cells. You must replace the water you lose throughout the day by urinating, breathing, perspiring and having bowel movements. In addition, consuming water can help you resist infections and aids in the digestive process.
