Just skip a day of drinking it and drink water or something else instead. If you go without it at least one day and break your daily habit just once, then it'll get easier and easier to not need it at all. But then once you give in just once, you'll want one every day again.
At least that's how it is with me. I'm an on again, off again pop drinker, and I'd like to quit completely because of all the sugar, but pop is just too refreshing sometimes.
