When I was a kid, every time I drank a fizzy drink, I swallowed it in a way that made it go up my nose. It confused me, plus my mum didn't believe me. Later in life I think I talked to someone who had a similar experience. It took me time to develop a taste for fizzy drinks, but I did. I don't drink the sweetened ones normally, and I ALWAYS drink Pepsi Max, I have one here now.
The gas in your nose was carbon dioxide. When bottled stuff is pressurized, the carbon dioxide becomes carbonic acid, and when the pressure comes off, the bubbles are carbon dioxide. The carbonic acid is what gives the drink the "sharp" taste. I don't know what's in Pepsi Max. I like plain, sugar-sweetened Pepsi, complete with the caffeine content.
