I think you're over-thinking it.

Personally, I take 5g every day. No loading. I don't think you really need to drink a lot of water all day when taking creating but you're supposed to take your creating with a lot of water (at the time of consumption) to ease absorption and avoid the stomach pain.

I don't think drinking water is going to tax your kidneys, really. They aren't really filtering anything since it's just pure water. If you are a healthy person then you would have to drink A LOT of water before anything would actually get damaged, IMO.

So, if I were you I would take 5g once a day with quite a bit of water and otherwise I think your water intake should be normal.
