Been drinking tons of Pepsi since I was a teenager for the caffeine. Can’t stand artificial sweeteners so I’m kinda hung up on the sugar too. I get the Real Sugar variety when possible. In order to cut back on the caffeine so I could sleep better I started drinking IBC root beer in the evening. It’s made with Cane Sugar as prominently displayed on each bottle. Helped a lot for getting more sleep. Still consuming too much sugar though.
ETA: not all root beer is caffeine free.
