Some people have a gene that makes them hyper-sensitive to caffeine. You either try lowering the dose or just no amount may work for you.

Drink enough of it and you’ll wonder how to better tolerate not having caffeine when the headaches start.

With consistency. Whether I have 1 cup of coffee in the morning, or drink caffeinated beverages all day, the key for me is to do that consistently, or suffer dire consequences. Ramping up, I can’t focus and anxiety attacks. Ramping down I get migraines.

Woe betide me if I am on a ramp down and find myself having to take an Excedrin or three. That spike keeps me up for days.

Eating something. Caffeine while on an empty stomach is no beuno at least for me anyways

I smoke some crack before drinking coffee…

That way I didn’t feel the effects of caffeine…
