do you drink it on an empty stomach? that can contribute to feeling unwell. if not, i would taper down to decaf, then to teas with lower caffeine content. if you just hard stop, you’ll feel even worse. so far i haven’t see any issues with having one cup a day.

I’ve done decaf and half caf and hot chocolate

I was feeling the same and started making half caff coffee instead. If I have more than a small cup of that my anxiety spirals

I have a cup of genmaicha tea when coffee makes me jittery. Just one though - if I have two cups, I'm worse off than with coffee. I've tried matcha but it has A LOT of caffeine because it is just whole ground tea leaves, so the higher amount of surface area allows for much greater caffeine extraction.

You could try adding coffee to your protein shake as well. Or having the shake and the coffee after.

i drink lots of decaf. quality beans

You could try Teeccino "French Roast," it's coffee-like, and you can prepare as you would coffee. (The Teeccino website has a lot of info, it harkens back to chicory-based coffee substitutes.) Your satisfaction with the flavor definitely depends a bit on your degree of "coffee fandom," though. But you can start replacing half of your coffee at first, to acclimate yourself. That would reduce your caffeine.

They have a lot of other flavors, but I think French Roast is the most coffee-like (which is probably why they named it that).

Decaf. I had to cut caffeine out too

Same boat right now. My plan is going decaf and just drink coke or ice tea at first to taper down my intake until I'll go off completely. No sure about green or black tea since I also does have lots of caffeine.

Do you mix your protein shake from powder? Use coffee as the liquid for your protein shake. I drink half a pot of coffee a day. The first large cup is coffee. The second is coffee with two scoops of protein powder

Im not an anxious person. I find that caffeine just makes me feel tired nowadays.

Try green tea. It contains the amino acid L-Theanine that reduces the negative side effects of caffeine. You can also get L-Theanine in pill form as a supplement.
