Can water actually fill someone up like they ate a meal?!
Answers: My friend told me it could. If you can how much water does someone have to drink?
Yes, but it can be very bad for you, if you drink too much, then your body cells can get super saturated with water and you could die. Because your body can't absorb straight water quickly, you get the "full" effect; you need salt as seen in sports drinks i.e. Gatorade to absorb it efficiently.
The supersaturation of water has been seen many times with people who do Meth, a side effect of it is the feeling of water going down your throat, it's supposed to feel really good, and people in the middle of a high won't notice how much they actually drink until it's too late.
Yes, but without the necessary nutrition.
Too much of water is bad for you - 2 litres a day is recommended.
Actually yes !!! but after drinking that amount of water you will have to run for the toilet over and over again.
quantity of required water depends upon environs. In dry weather where eevery exhalement results in loss of body moisture . one needs more water as compared to one whee air has high humidity.
