i normally drink 165-198 ozs (5-6 liters) a day. i have water with me all the time. i drink both tap water and bottled water. i have been LC'ing over 3yrs now and it just comes naturally and i find i am actually thirsty if i go too long without a drink. i have 1 or 2 cups of decaf in the morning and the rest of the day it is just water and i was one who used to drink about 100 oz (3 liters) of diet coke a day!! i didn't like water at all when i started LC, didn't even take my meds with water, then i started off by taking my meds and vits with tap water and started replacing the coke with unflavoured carbonated water and then after about a year i switched from carbonated water to bottled plain water and increased my intake and now as i say i drink water all day and of course feel it is so much better for me.
