You do you. Don’t worry about the purists if it helps you stick with it. I drink broth on most days and don’t worry about the few calories as this helps me get more sodium in my system. Too much snake juice and I get gastro issues, plus it tastes like 🤮

you may just find that if you drink coffee you may have to drink water alongside it as it may mess up your gut during your fast ie give you cramps gut pain
then again if you don’t do coffee for the first 3 days of your fasts hello major headaches
