This thing works, although I can not be sure if it is a placebo affect or not. I rarely get migraines, so it took me a few weeks after I got this product to test it out. BUT the other day I was getting a migraine, so I took this medicine with a glass of water, and soon after, my migraine went away! Now, I cannot be sure if the headache I had was actually a migraine or simply a headache caused by thirst, which happens to me on random occasions, so I cannot be sure that it was the medicine that worked or if it was the water that helped. But hey, this thing seems to be natural and when I took it, my problem went away!
