Dumping excess water with methylfolate?

I am familiar with the concept that you can start dumping excess fluid when you start getting your methylfolate intake levels up high enough.

Generally this is referring to increased urinary output, but I notice that I can also get frequent bowel movements that are almost completely like water.

Always thought increased urinary out put was fine, but watery bowels was too much folate.

Could I have been wrong in this assumption & that actually both are avenues for dumping excess fluid?
