How to stop being so thirsty?

Ever since I attended a workout program or whatever it's called, the coaches have been telling us to hydrate and so far I have been drinking water for a few weeks now and it's starting to be a habit of just drinking water all the time. And before I go to bed(which is the worse time to do this) I start drinking a lot of water I always keep a water bottle by my bedside and I drink so much water that by the time I get in bed the bottles all empty and I have been wondering how I can get myself to not drink so much water and why I'm drinking so much water and I don't even like water very much it feels like my tongue just wants water soooo bad. So plzzzz help me it would really mean a lot. :)
