Why does drinking water makes ME extremely hungry? anyone else?

First let me tell you a little about myself. I'm a male under 30. I weight 170lbs which is not a lot for my height which is 6'5". In fact, i am very skinny. I have noticed my metabolism is starting to slow down. I figured I'd start drinking water to keep me healthy and to "help" lose an inch from my belly. But drinking water makes me really hungry. I have always had breakfast/lunch at sametime (separately), and sometimes dinner, with VERY little snacking between . It has ALWAYS been very easy for me to diet, or even going a day without eating the major meals if busy. I normally don't get hungry between bkfst and lunch (even when I snack, I just snack for snacking.) Anyways, these past few days I been drinking lots of water, and it makes me, and keeps me VERY HUNGRY;the hungriest I ever get .I know all I have to do is quit drinking water, but I'm just curious as to why I feel this way. And is anyone else experiences the same.

BTW, I'm still eating the same, at same times. Still exercise the same, same times/days. I haven't changed anything besides water consumption. And happens ONLY when I drink water. (6x 16oz bottles a day) THX.
