Ok im not the most tidy guy in the world but this demonstrates that I do drink my 2L of water a day. Its sparkling water but it is just water. Adding your tea, coffee, juice or whatever to your water intake does not count in my book. I usually carry about 30L in the car (which is my place of work) so I never run short. People do look at me a little funny buying 15-20 2L bottles of water at the supermarket but I dont mind.
Water water water and more water. Its all sparkly!
