LPT: Don't go to sleep without getting a bottle of water

I started this habit last year when I was going to sleep at 12am and waking up at 7am. I got a habit tracker for water and one night I forgot to drink water so I didn't fill up my bottle for the night. Next morning, I felt like I had a big rock in my belly. It was so uncomfortable. I didn't know how much water I drank the night before. It was about 400-500 ml. I learned that it was a lesson to not go to sleep without a bottle of water. Now I always carry one with me.
