idk how to not drink and idk how to bring more i played more and saw i could 5 more bottles i think? but it still wasnt enough :(
There are two actions which gives you different water items. "Extract Water" gives you small water bottles but has a limited number of uses, while "Take Water Pouch" gives you a water pouch and has unlimited uses. So as long as you don't drink all the water bottles early on, you can take 5 water bottles and 5 water pouches on your journey. And that is enough water to reach where you need.
