Oh sh*t! What are you going to do? I feel bad for you, man! Seriously, please Google it. I don't know what it's called but try searching "oxygen to h2o" or something like that. If there's a store nearby, you could purchase water there :/

Restrictions? Wow... Like, you can only use a certain amount a day? Dude, you should get a water converter. It converts water in the air to ordinary drinking water.
