Who makes use of water therapy to fix mood swings?

[Heatman]

A friend of mine told me about making use of water therapy in order to work on her mood swings. She told me that whenever she is having a mood swing, she try as much as possible to drink a lot of water and this helps to change her mood to something better.

I'm not sure if this works for so many people but I would like to know those who have tried it to know how effective it works.
