I follow the science, 2-3 cups of coffee a day is what was found to reduce mortality so that's what I drink. The amount of caffeine in a cup of coffee actually varies significantly, 70-140 mg, but at least 3 cups is most likely still below the FDA's recommended maximum of 400mg.

And I get headaches in the morning sometimes, coffee + aspirin has been very helpful.

I think anymore than 3 cups and you'll still have caffeine in your blood system at night, which doesn't seem healthy. I think it's easy to fall into a pattern of increased caffeine use through the circular pattern of drinking too much and getting terrible sleep, then ramping up the dosage the next day in order to feel awake.

I think it's important for people to recognize this little quirk and not to spiral into a pit of its tasty dark magic.
