I drink both coffee and tea daily. At home I make espresso/latte in the mornings and red or green tea at night, and at work I make very strong coffee. For a few years I would drink espresso/latte at night, before going to sleep. I've tried a few times to switch over completely to tea but it just doesn't work out for me. I managed to go an entire month of tea at work before I quit and switched back to coffee. Even if I make the tea extra strong it tastes watery and seems like something is missing.
