Do I really have to purify all of my water? At a certain point it just becomes time consuming!!
Well, technically you don't have to purify all water, but it's risky :)
Not all water is bad, though. Unidentified water can be either pure or impure, so there's a chance you'll be fine drinking unidentified water. Purifying just makes sure it's safe.
You can usually be safe drinking water you find inside bottles, assuming it was a sealed bottle and not something a creature placed in there. Such bottles have the water already identified as pure if you examine the water.
You can also use water purification pills if you're in a hurry. They're hard to find, but easy to carry.
Antibiotics are another way to go. You can drink lots of impure water, and usually be fine taking some antibiotics after (antibiotics will remove cholera, no matter how much you drank).
Finally, you can boil up to three water at a time in a pot. There's a bug that makes it a bit touchy (sometimes only 1 or 2 will actually boil, instead of 3), but it can speed up large batches. I hope to fix this in the future, once combat and storyline stuff are done.
Hope that helps, and good luck!
