Water~ Water good, I mainly drink water all the time.. for a non boring answer, I'd say... root beer~ I don't really know what brands are better since I usually only get root beer when dining out with people, but root beer good in general... (lately I've also been drinking Root Beer-flavored Olipop regularly which is pretty alright for some extra fiber)

Fun fact: I have never had alcohol.. I admit, part of me is curious, but then part of me is like "yeah no my father was a violent heavy alcoholic and I'm worried I'll become evil if I drink and/or become addicted and destroy my body like Nagata Kabi"
