For folks who wanted to know how I came up with my hydration plan, it's from this Huberman Lab episode: https://www.youtube.com/watch?v=IAnhFUUCq6c&t=8195s

Too much water will cause minerals to leach. You have to add electrolytes and/or salt to your water to balance. With proper water, you won't need that much water anyways.
Andy Galpin is awesome
