once gave me this example.... If you have not been drinking water your tissues can get dried out, like a sponge does if left out. When you then pour water on it, it can at first only absorb very little, and the rest runs off. After a while though the water is absorbed more easily. I have always noticed that when i go through times of little water intake, then start drinking proper ampunts of watter, I have to urinate all the time! After a few days it will get better, as your body gets used to the new moisture level. Keep drinking! Blessings!
