Approximately how many days can you live without drinking any water?

-It is extremely difficult for me to drink water on a daily basis i usually have no more than 2liters a week.I get migraine headaches everyday and have had urinary probems i believe is because of the lack of water.I also have a bowel movement maybe once or twice a week and it is usually either really runny or very hard to pass.I also rarely eat any vegetables,fruits,or pretty much anything healthy.I grew up this way and am learning i have a very long way to go as far as health.But each time i drink water i feel ery sick and its accompanied with headache.For example,today i drank 1liter of aquafina water and then i felt dizzy and very sick to my stomach and had two bowel movements within two hours that felt similiar to having a stomach virus.Loose and runny.Advice anyone?Less than a week. And work to get your diet better, this will help your nausea and diarrehea drastiacally in the long run.Well it depends on the conditions but generally 3 days.
