I thought this said extra strength? Not to me it wasnt. Just for an everyday headache I took these to get rid of it and was that every a mistake. It took so long for them to kick in (if they even did, I think by that point my headache may have went away on its own.) I would never try them again. Obviously there is nothing thats going to take away a headache in a second but when you waiting 45-60 minutes to just start to get results it can feel like forever when your in pain. I wouldnt recomend or try again.
