Since this is a tea forum, I wonder what will reign supreme?
I don't drink alcohol anymore, although if I still did, a dark beer would be #1.
I drink about one soda a week and probably less than that of fruit juice so that wouldn't be it.
I have to admit, though, a big craving for milkshakes. That would be something I don't think I could give up...tea is very very close behind that, though.
