I have suffered many years from painful periods. At first I took copious amounts of advil/aleve (2 advil every 4 hours or 1 aleve every 5-6), which worried me, so then I went on birth control for two years. A month after starting this nutrition program I went off the birth control, and I noticed that I no longer had the severe pain anymore. I do have some pain every month, but it is completely manageable without the use of any sort of pain reliever. Furthermore, I have been on this program for over a year and have not taken a pain reliever for anything since then. We do not even keep them in the house. I know that this program is the reason for that.
