Question

Lately, I’ve been constantly needing to drink water and spending most of my time in an air-conditioned room, without going out. Yet, despite drinking so much water, I don’t always feel the need to go to the bathroom. The only time I do is in the morning when I wake up, and it can also be postponed until noon. What’s going on? This has never happened to me before. I would appreciate some expert guidance. Also, I’ve been eating less lately, just about half a watermelon at most. I always feel like my mouth is dry and lacks taste, as if I’ve eaten too much sugar, and without drinking water, my mouth feels extremely dry!!
