Hey, there! Welcome to BN!
Take a look at this thread, it may help you with your search for a "Sprite Cologne"
As for vanilla, if you're looking for pure, straight vanilla, give Pi by Givenchy a go. Another fragrance I really like with vanilla in it is John Varvatos by John Varvatos. It's not a gourmond, but it's got a dark, syrupy vibe with a good hint of vanilla in the base.
Welcome to the club! Hope this helps
