Yup! By the latter quarter of my time in college I was up to 10 cups of strong af black coffee before midday, and a quarter pack of cigarettes. Then the pandemic hit and it was harder than ever getting cigs and was forced to quit cold turkey when I got infected. Not dealing with traffic also made the anxiety I got from coffee not managable and had to tone that down too.
I've managed to reduce my coffee intake to once a day at most, early in the AM. Mostly for the flavour. A good shot of espresso with condensed milk does wonders, but will leave me somewhat jittery since my resistance has dropped so much.
I kinda miss drinking coffee from 6am to 10pm.
