When to drink water.. after meal or between meal and Why ?

Hi, in most of the health articles most of the people suggest the amount of water which has to be drink by a proper human body in order to get all the things work properly. But i want to know that what time is correct to drink water after meal or before meal or between the meal please suggest the best time.

I think you must drink water after half an hours of taking the meal. In a days you must consume more than 2 litre of water and above that if you feel thirsty then have it. Excess of anything is harm.
