Can I use distilled water to make bac water? I can't seem to find sterile water without a script. I know I can order it online, but the whole point of making my own was to save money. But if I have to order any more stuff online and pay shipping costs, it would have been cheaper to just buy the bac water in the first place. So will distilled water work or am I gonna have to eat it on this one? I have seen videos online of people making it with distilled water.
