Water intoxication

I am a male, 19, 175 cm tall and weighs 71 kg
Sometimes i drink about 1 liter of water and then after an hour i drink 1 liter more.
Then my head gets a bit dizzy and i keep going to the bathroom. I'm pretty sure i drank too much water, but would i get brain damage?
I'm really worried.
Also, i usually don't drink much during school, so i get very dehydrated when i come back, as a result i drink a little more than 2 liters of liquid in less than 2 hours. Would this sudden intake of water after dehydration cause more damage to my brain cells?
I would really appreciate it if someone can tell me.

Hi,

Thanks for writing in.
Water intoxication occurs when a normal healthy individual consumes about 10-20 litres of water in few minutes. This occurs due to disturbance in the electrolyte balance and subsequent brain damage.
In your case it will do you good to maintain a steady intake of water throughout the day in order to avoid dehydration but the risk of water intoxication is certainly not there.
Hope this helps!
