Around 5 hrs to fully metabolise caffeine. Physically you would be fine in a day.
The habit, however would take longer to get over. That depends on your psychology, I know I can’t just replace my morning coffee with tea, because it doesn’t feel right.
I usually have my last coffee at around 2pm, so by the time I get up in the morning, there is no caffeine in my system. The feeling of drinking coffee and tea is different for me, it’s not just about the taste.
