Not sure how you get yours, but I’ve always been a coffee drinker. I cut my caffeine way down by slowly mixing more decaf into the grind when I make the pot. Instead of drinking half a pot or a pot of regular, now I get the equivalent of about a cup or cup and a half if that and it was easy to do.

If it’s soda you could experiment with drinking it from a big cup and doing the same trick mixing in decaf maybe?
