Naproxen
"Girls... If you want to be able to function and actually get out of bed this is the solution for you. I have unbearable cramps to where I'm stuck in bed and cry all day from the pain. I've tried everything over the counter and nothing has worked. I was prescribed the 550 mg and my life has changed. Even though there are times where I still have pain it's not as bad as it was. I don't experience any real side effects except sometimes I get a little tired, but it's not horrible."
