I also like citrusy stuff like lime/lemon or orange seltzer water, it's very refreshing. I like cranberry juice too, because it's kind of tart.
I have a major sweet tooth so I love stuff like pastries, ice cream, chocolate, etc but I try to limit that.
One of my favorite flavor combos is sweet and spicy, such as getting orange chicken from a Chinese takeout place and putting red pepper flakes on it, it's the perfect combo. Or sweet and sour chicken. Sweet/salty is a good combo too, chocolate covered pretzels, pizza with ham and pineapple
Lately I've been craving the candy sour patch kids
