I have had HORRIFIC period pain my entire life. Popping pills all day long with no relief, hospital visits, prescription pain killers, none of them worked, and birth control isn't an option for me. This thing has literally changed my life. As a preschool teacher, when I get period pain and it doesn't go away, not only am I affected but so are my students because I can't care for them the way I usually do and should. Now that's not a problem anymore. I feel like my normal self. The only reason I am only 98% pleased with this instead of 100% is that: 1) I have more sensitive skin, and the gels can get really itchy for me. 2) Sometimes I need to have it on so high that it does feel like little shocks instead of tickles. However, overall, I will be a life-long customer. This has changed my life.
