Unfortunately trying to limit or stop caffeine consumption, any flavor alternatives?

I’m an energy drink lover, but have started to realize I’m getting pretty bad caffeine withdrawals, and I just feel better physically when I don’t drink caffeine. I would love if the main brands had the same flavors with half or zero caffeine, as the flavor is a big draw for me. I usually drink them as a tasty treat rather than the caffeine itself, so i’d like to find some low caffeine alternatives.

I’m looking for drinks with zero/low sugar, carbonated, with lower or no caffeine, that have similar flavor as some of the big energy drink brands. Right now I love the Ghost sour black cherry, ghost and monster peach, C4 blue jolly rancher, and Rockstar Mandarin orange.

Any suggestions are welcome! As far as product availability I live in USA, midwest.
