so true, I also quitted my 3 daily coffees and now I take just one cup in the morning, so to optimize good sleep (I think I'm slow AF in metabolize caffeine, so even the second cup after lunch would give me a bad sleep)

I consume large amounts of caffeine (from root beer & peach Redbull) but a cup of coffee gives me jitters every time. I've tried to make sense of it but can not.
IDK, maybe you are sensible to caffeine and in these beverages there is just a bit of it, while the coffee you take is very strong.
I think a 20oz bottle of Barqs Root Beer has close to the same as a cup of coffee. I'd assume a 12oz Red Bull energy drink has more than an average cup of coffee. I could be wrong tho, that would explain the coffee jitters.
