I cut out most soda long ago, but one recent drink change I did manage - I like hot chocolate in winter, and I tend to like it syrupy, so it's not exactly health food. I tried making a glass of hot water on a cold day instead, as an experiment when I noticed it was an option on the coffee machine at work. Surprisingly, I liked it almost as much - it has the nice warming effect, and it tastes much nicer than lukewarm water. I suspect that'll save me a lot of calories over the average winter, plus it''ll let me consume way more hot drinks than I otherwise would on cold days.
I've noticed that at least for myself, things which are very warm/hot and things which are very cold (by the standards of food) taste better than lukewarm things, independent of flavor. I'm not sure whether this is a general principle, but suspect it is.
