I normally drink about 4-6 litres a day. And I have been absolutely fine. I think you can only do damage if you drink a lot in a short space of time and not going for a wee when you need it.
I can't easily drink 1.5 litres quite quickly and always have done. Even before the diet. So maybe it's just what you get used to xx
