Once you wean yourself off them (takes a couple of weeks at least for your taste-buds to re-adapt to the taste of normal drinks), and you have them again after some time, they taste disgusting,sickeningly sweet, even the sugar-free types. You just have to give yourself a break and a chance. I would rather buy a natural un-concentrated, undiluted, unsweetened, and generally untampered with fruit juice (which it has become more and more difficult to find!), then top up half the glass with sparkling water, far tastier than the canned stuff. I normally go with cranberry juice - for the taste as well as the benefits.
