I tried to give up my morning coffee and switch to tea but I just ended up drinking a ton of tea. Presumably my body trying to get the same amount of caffeine. Seemed pointless.
It isn't pointless. While you may consume the same amount of caffeine in a day, the amount in your system at any one time will be lower--especially because caffeine in tea is released into your blood more slowly than caffeine in coffee.
Draw an analogy to booze. Yes, it is totally possible to drink enough beers in a day to consume as much alcohol as you would drinking hard booze. But your blood alcohol level is unlikely to reach the same level as it would drinking shots. I know people who've gotten drunk on beer. I've known people to pass out from chugging beer. I've never heard of people dying from alcohol poisoning from drinking beer.
The difference between coffee and tea is sort of like this. You can get as much caffeine in your system
from tea as coffee if you drink 2-3 times as much tea as coffee in the same amount of time as you would have taken to drink your coffee. But as a practical matter, most people won't do this. It's sort of like spacing out your alcoholic drinks. If you consume three drinks over the course of three hours, you'll probably be considerably less drunk than if you consumed the same 3 drinks in one hour.
The amount of caffeine in your system at any one time matters.
