Usually you get thirsty. Minor dehydration can cause headaches, dizziness and tiredness. Chronic dehydration can harm your kidneys and liver and cause constipation. Prolonged dehydration can lead to low blood pressure, rapid heart-rate, loss of vision (leading to permanent blindness), Seizures and loss of consciousness (eventually leading to death)
You will be very dehydrated, but not suffer any permanent injury unless you remain without sufficient water for many hours, or are exposed to high temperatures.
When you get dehydrated, and your blood pressure goes down, you might pass out if you move too abruptly.
Over time, too little water intake (or too much) puts a strain on the kidneys, and can injure the bladder and urethra as well.
If you drink too much water you may suffer water toxicity which can be fatal.

It is very good too drink alot of water. BUT don't drink it all at once you can drown yourself. Drink it little by little.
Yes. Too little will make it darker. If you drink too much, your body will remove more. If you drink too little, your body will hold on to more.
Your mouth gets really dry and its hard to drink water.
Okay, here's what I know.If you drink WAY too much water, you can get water intoxication. This mostly happens to athletes, and young infants. Infants might drink many bottles of water, and athletes might drink too much since, of course, they sweat a lot.So, you can sort of "drown", but only technically.
You can get water intoxication, which can effect the balance of the electrolytes in your body and can cause swelling, faster heartbeats etc.
When you drink too little.
You will die.
You will vomit!
Drink a little water and wait it out. Take it easy.
