Honestly, I've never had a day without caffeine in about 12 years. I'm going to try going without for a few days to see how I feel but even if I don't have my first cup an hour after waking I feel bad.
Coke Zero isn't great I agree, but I do fasting and it helps me feel satiated during a 22hr fast.
Have you noticed your sleep better btw?
For sure. Caffeine wrecks sleep, even the small amount left in decaf.
Do a slow taper off of it. Took me a whole month to get to zero and that was still rough. Going without it for a few days will make you feel like crap but if you soldier through you will eventually get better.
Oof! A whole month and still feeling rough
If you want to fast 20+ hours and not be hungry, just eat fatty red meat. That's what I do, and I can easily do 23+ or longer with minimal discomfort.
I have my own protocol that works for me. I've been fasting for years. I think it depends on the person
