Why it matters
Caffeine tolerance is real and it builds quickly. But there's a difference between caffeine tolerance and caffeine dependence. If you're relying on coffee just to feel baseline normal, you've likely shifted your adenosine baseline and the coffee is now just filling a deficit you created. There's also the CYP1A2 gene factor — slow metabolisers process caffeine differently and the timing of their last coffee matters far more than they realise. Finding out which pattern applies to you changes everything about how you use caffeine.
When Normal helps
Normal tracks your caffeine consumption — when you have it, how much, and how you feel before and after — over time. It finds whether you're on a dependency cycle, whether your timing is the issue, or whether something else is driving the fatigue that you're using coffee to fight.
How Normal finds it
Tell Normal every time you have coffee and when. Tell it how you feel before and after. Over a few weeks Normal finds your specific caffeine pattern — what's working, what isn't, and whether the coffee is solving the problem or masking something bigger.
