I have been a migraine sufferer for many years now. My migraines are really severe and are extremely painful. I purchased this medication to try and find something that would help stop my migraines. While it was successful in getting rid of minor headaches for me, it was not powerful enough to stop my migraines. I took two of these when I first started getting a migraine. They did not do anything to stop my migraine from coming on. They were simply not powerful enough to stop a migraine. If you are looking for something to relieve a simple headache, these would do the trick. However, I would not recommend them if you get severe migraines. They did nothing to stop mine. Effectiveness They were not effective for me at all. They did not relieve any pain from my migraines at all. Ease of Use I took two with a big glass of water. They are easy to take but do not work. Immediacy I never got relief after taking these.
