My daughter didn’t believe that it would work, but was she ever surprised! She used to take a very high prescribed dose of Naproxen (375 mg) for her horrible cramps that would leave her nauseous, rolling around in pain, unable to stand up….for about 3 days every cycle, and even those meds wouldn’t fully work. She was very skeptic and only agreed to try Cramp Cream when I ordered the sample size. Five minutes later she came out of her room and exclaimed “IT WORKS! My cramps are completely gone!” It lasted for hours. She was amazed, has used it since, and swears by it. She even convinced my sister to try it since she suffers horribly every month, too. We ordered the large size of Cramp Cream and I will be using it along with her. (I also used it on my jaw for lower tooth pain and it worked!) We have set up her school bag with a small container of the cream so she’s ready anywhere she goes. I could just cry thinking back over the last several years at the incredible amount of school days missed due to cramps so bad that no one believed her. (How many days can you miss due to your period and still have teachers and school admin believe you?) I wish this had been around when I was young and taking huge amounts of Midol. I’m just so thankful my daughter has this and we are true believers now. THIS STUFF WORKS!!!!
