How do I get myself to drink more water?
user
Try a few weeks of drinking water with breakfast, lunch, and dinner, if you like.  You could drink water throughout the day.  Or you could drink all your water in one sitting, and not leave the bathroom for a while.  Or maybe you want to limit your drinking to certain times, such as an hour before bed.  Or some combination of those strategies.  I could continue to generate more options for you, if you like.

Why would I drink in the bathroom?

Some people enjoy the novelty of it.  It’s a nice break from the regular routine of doing other things.  Some find it relaxing to slow down and enjoy themselves.  It’s different from other things they do during the day.  I understand if it sounds silly to you, and I don’t mind you not taking this option into consideration.  I am happy to go on talking with you if you want to.  I am just offering some possibilities for you.
