How much water should you drink per day?

Is coffee and tea and other liquids included??

Will this help with constipation?

Also when I drink allot of water I go to the bathroom every 10 minutes, will this regulate???

Generally 64 oz. (1/2 gallon) is a recommended MINIMUM. Caffinated drinks are not counted towards that total (because caffine is diuretic, the net effect is as though you hadn't consume it in the first place).

Increased intake of water does help many with constipation.

Try increasing the amount of water gradually, to minimize more trips to the bathroom, but your body should get used to more water quickly enough.
