Naproxen
"I had really bad cramps. I tried several things, and nothing seem to work. When I get them bad I have  to miss school and just lay in my bed with  back pain, headache, barf etc. So I had enough and decided to go to the doctors. My doctors prescribe me for naproxen. On the day of my cycle I took the pill and in about 30 minutes I was pain free. I took a nap and it felt like I didn't even have my period! I definitely recommend this, I am very pleased and this will be my go to every month. but remember, what works for me doesn't work for all."
