Yes that likely would be. I guess the main issue is the really heavy sugar content in many drinks more than the carbonation. I find that it's the drinks like cola that are really brutal but there's also other drinks that are particularly sugar packed but not carbonated. I've been trying to make a conscious effort to not have things like this and it's been very positive overall.

Yeah, I did the same and I rarely have soda anymore. But you don't have to give up carbonation altogether if you don't want to.
