Why do I struggle to drink water?

This is a rather baffling concept to me, even as I experience it. We all need water to survive. So far, I've succeeded in drinking enough water that I don't keel over and die.

I want to be able to sing, and have healthy non-psoriatic skin, and have at least a semi-active lifestyle. All of these things require a considerable amount of water going in and out of the body.

Feels almost like I'm under-compensating now.) I think part of the water avoidance is also the amount of effort it feels like it takes to physically get up and go to the bathroom.
