Hello all, from a newbie, although I've been reading this site for a long time and find it FAR more informative than others.  Indeed on one site which is high on Google I proposed a question and was answered with nothing but sarcasm.  OK so my question.  I've just started taking whey isolate twice a day. The dosage is 50 grams mixed with 300 millilitres of water. The times are just after my afternoon gym session at 4pm  and just before going to bed.  However I find that I'm now getting up 5 times during the night to pee! My kidneys are OK as I once had kidney stones and am very aware now. Any suggestions please?

Whey is not specifically a diuretic. Protein on the other hand (of course whey is a form of protein) can cause water loss. Typically when bb's r dehydrating before a show they eat several protein only meals which causes diuresis.

Thanks PJ, that is re-assuring. I'd better get a "po" under my bed.
