There's this new water being produced in british columbia, canada that is going to hit the market at least here in ontario soon. I can't wait to try it. It's called Happy Water and it contains naturally-occuring lithium carbonate salts from a spring somewhere in BC. They claim it can raise your mood. Lithium is also a well-known treatment for bi-polar disorder. Hopefully it's not too expensive but I will definitely try some when it comes out. I just hope I won't have to drink 10 gallons of it to feel something lol. I think lithium water is common is some states in america but I'm not too sure about that.
