I usually have quite concentrated urine as I don't tend to pee much. However last night I constantly needed to pee and everytime there were large amounts of clear urine through the night. No infection (I'm on abs for something unrelated anyway) but I must have gone about 10 times, all clear like water. Finally fell asleep about 3am. First morning urine was dehydrated like an orangey brown. What's going on? I didn't overhydrate yesterday either.
