I believe it can be counted as water, my center told me that walmart has some flavored water (i don't care for it) but also told me i can add crystal light. I just think it can't be counted with your protein drinks
I was told a minimum of 64oz has to be plain water...of course that all depends on your counselor. Sometimes there are inconsistencies...I personally make sure that amount is plain....then I add flavor.
I was told that a minimum of 64 ozs has to be plain water if you just can't handle plain water then you can put a tiny squirt of lemon in it, but they really prefer plain. the reason I was told was because if you put flavor in it your kidneys still have to filter out that flavor but plain water runs right through without needing filtered. However I don't quite understand this because if I drink 20ozs plain water followed by 20 oz crystal light don't these mix in my stomach and now my plain water needs filtered too? I'm not sure, most of my water is plain water but some days it is really hard lol
