Just a warning - our science teacher forwarded an email to us from a health board, warning against the over-usage of plastic bottles. Apparently if you use them more than 2 or 3 times (refill) the plastic releases toxic cancer-causing chemicals, as the plastic from mizone, H2Go etc bottles are only intended for one use. I'm terrible with my water intake, I can't remember the last time I had over 3 glasses in one day, but this thread has definitely motivated me!! Bring on the good skin- I so hope it works! I know Jessica Alba drinks 3 or 4 litres a day..
