Are there any flavors that just go together for you - like chocolate and peanut butter? I have one that got started by chance after a meal - probably something from Sonic. They give you peppermints with your food, you see.
So my flavor combination is peppermint with Diet Coke. It’s to the point now that if I have a peppermint I have to have a Diet Coke. The carbonation in the Coke makes the peppermint come alive!
