Review (5/5): It really works but...
I am not a headache person but I am super sensitive to even one aspirin. May I recommend that you start with less quantity than what they suggest and then go from there. To this point tho, I am a smallish person, weighing 108 @ 5'2". It really does work as I am able to get to sleep and stay asleep. The headache goes away once I get up and am moving.
