I barely drink soft drinks, but if I do, I usually have a Coke Zero. Is Pepsi Throwback a regular thing? I see it sometimes in supermarkets and got it once and it was great. Nice to have real sugar rather than HFCS. Again, I don't drink it nearly enough to worry, but you do hear things every so often about aspartame that are turning me off Coke Zero.
Yes it's a regular thing, been around for a while now. Some regions sometimes don't have it widely available though. Here in Phoenix most places have both Pepsi and Mountain Dew Throwback.
