This is such an edge case on quitting a caffeine addiction. 2 liters is an INSANE amount of coffee to be drinking daily.

Kudos to you but let's not pretend this is the average experience of people breaking even much milder levels of caffeine consumption.

I did my research before letting coffee loose on my body.

The coffee acts by blocking tiredness/sleep receptors on the brain, so brain builds more of them to work normally. This is how coffee dependence and tolerance builds.

When you stop coffee, brain detects that the number of receptors is too high and starts to break them down. This is why you get the headaches.

That "one week" period is not an edge case, it's the science of it. If it was proved to be harder on that research, I'd never let my body to reach 2L/day levels.

Was this research similar to you drawing conclusions about nicotine based on the handful of your friends that vape?
