Do I have to drink distilled water for everything, or only for when taking the certain minerals? We installed a very expensive water filter on my tap water. Will I not be able to use it anymore? I sure hope so.

I recommend distilled water for when you take the minerals. You can drink your regular filtered water the rest of the time. What type of water filter do you have in your house? Is it reverse osmosis? Because if it is reverse osmosis, you can use that water with the minerals instead of distilled water. Reverse osmosis is just as good as distilled water.
