Another small step in my attempts to increase my fluid intake/water intake was to swap caffeinated tea and coffee for decaf or herb tea, mint tea for me. Now I only drink caffeinated beverage once a day in the morning and not the rest of the day.
I have increased my fluid intake and I sleep better by not having the caffeine in my system.
If you have trouble sleeping then this small step might work for you too.
