Best tip I have read about drinking water did not come, for me, from LC forums altho it has probably been mentioned all over the place. I don't know where I read it, maybe even DADNR? Iced water is easier to drink. It tastes better and goes down easier.

I fill up one liter water bottles about half way, then fill them up with room temperature water. Everywhere I go, I can have iced water. I drink all day and I drink three liters. One you build it in to your routine, it gets easier and easier.

I read a news blip recently announcing that someone has invented ice cube trays with long, rounded ice cube molds to be used in water bottles. Freezing water in bottles is cheaper.
