Excedrin Extra Strength - Box of 4

Took one of these for a tension headache that had been building all afternoon and it was gone in about twenty minutes. The combo of acetaminophen, aspirin, and caffeine really does work faster than the plain stuff I used to take.

The caffeine in these actually makes a difference for my afternoon headaches, kicks in faster than plain acetaminophen. I stash a couple in my purse and the glove box so I'm never caught without one. Four boxes lasted me almost a whole year.

I keep the 4-box pack in my desk drawer, and the caffeine in these knocks out my afternoon tension headaches in about 20 minutes. Having four boxes means I'm never caught empty when one runs out.
