Once in a while, I’ll go through what is essentially a caffeine detox, or really, just a period of drinking less tea. What I notice is that consumption of tea over time trends up. This also means that I generally consume more and more tea over time. It’s sort of natural – you fill up the pot, and before you close it and start the process of brewing, you add a little more. This “little more” gets normalized and next time you add a little more again… and it goes up.
