Frequent urination very clear even though I haven't drank any water at all?

Something not right. Urine is made from the liquid u consumed. Can't be from nothing. Remember: tea/coffee/juices/milk/sodas etc. Are mostly water. They just contain colorings and sugars/junks. Also, most of the food u eat contains water. Quite a bit of it actually. So, if you drink lots of the above liquid, u make urine. And they can be clear. If not, u would dry up like a twig fast. Consult doc if u r concerned...
