I tried cutting it out for a while to see if it was causing some anxiety (it wasn’t, it was just the world and lockdowns) but went from 2-3 large cups of chemex a day to 0 for about 8 weeks and it was frankly…. fine? I didn’t even get headaches. I count myself lucky, esp so since I am back to drinking coffee haha
The odd thing is I didn’t even have headache first day, though I have experienced that another time (like when travelling and not having coffee). But this time I was having no caffeine (no tea, soda, etc either) and I did t experience any change. It gave me quite a surprise
