When it was out in Canada over the summer I went back and forth on it. My first impression of original was that it was really damned good and surprisingly creamsicle-like. Then I went through a short period where I probably drank too much of it and found it a little too sweet. Then I hung onto my last bottle for months and only drank it a little while ago, and was back to "why can't I have this all the time."
Still haven't found the Orange Vanilla general release yet in Canada, though. I did find a bunch more places with the Canada Dry Pomegranate Ginger Ale and a place with some bottles of Blackberry Ginger Ale and Crush Pineapple, though, so not a total wash. (also when did I decide I was really into limited-release pop, help me)
