Yes. As the song goes, "Too much fun whats that mean? It's like too much money, there's no such thing. It's like a girl too pretty,..." But for everything else in life, do in moderation. Plain green tea at 4 mugs of 12 ounces each day sounds ok. That means without creamers, sugars, or other sweeteners... and without tapioca pearls (boba). Drinking plain green tea is better than drinking sodas.
