Recently, I've tried to up the amount of water I drink, to a) hydrate during summer and b) eat less . I'd originally heard that one should optimally drink 8 glasses of water a day, but talking to friends, I've learned that this has been disputed, and 8 glasses was found to be too much? How much have you heard is the right amount to drink? How much do you actually drink a day? I recently started buying 1 Litre bottles of FIJI water, I really like its "non-plasticy" taste! What kind you drink?
