Unfortunately, I add 100 calories of crap to it. But I drink it slower than Coke and it’s at least half the calories of a 32oz (my other vise). I use it as a way to lower my calorie count, just a little.
If you ever want to try and ease off both those vices, I'd simply recommend buying a McDonalds coffee, buying a Starbucks Blonde Americano, and then taking them home and brewing a cup of the folgers instant with no additions. Get someone to pour them into identical cups, and have them play a shell game (move the cups around to hide which ones they are), then try them back and forth. Try to avoid anything with sugar in it for a few hours before. I bet you'll pick out some differences and maybe even like them, then if you want to try and delete the sugar from your coffee, avoid it in exchange for black coffee for at least a few months. It's not as hard as it seems, but it does take some time.
Then if you like, play around with easy home brewing methods like french press or pour over, grinding beans etc.. those were probably the most impactful things I tried when I went on the same journey. Grinding recently roasted beans before brewing was eye opening. I honestly didn't believe black coffee could be palatable, and was drinking Folgers with half and half from the big red can for ages.
