I bought my first bottle when I saw it sitting on a shelf in the medicine section at a local grocery store. Seriously, these pills are a miracle.I get extremely painful leg cramps that start in my feet or calves, or even worse, up my inner thigh from my knees to my groin. I've had many nights where they were so intense I was literally on the floor screaming in pain trying to crawl to the kitchen to get pickle juice and then followed by soreness for days.When I first found these pills, I was skeptical at first but that all changed after the first time using them during one of my muscle cramp attacks. Within a couple minutes, the cramping stopped. I was like, OMG!!! These really work!! Like a gift from the Devine. If you've ever suffered from severe cramps that feel like your muscles are ripping away from your bones, you know the dread and shear terror when that first twitch hits you and you know it's going to erupt in a full on cramp attack. These pills literally save you!!!I have since bought bottles for my elderly father, my boyfriend and another friend who suffers fromLeg cramps as well and they have all reported back saying these are freaking amazing and stop cramps right away.I even told my doctor about them because I'm also on a cholesterol medication that causes leg cramps and prior to having these, I was cutting back on my medicine because I couldn't handle the leg cramps. He was skeptical because he never heard of an over the counter pill that worked so well but was like, awesome of it works! Well it does. Buy these, you will be happy you did!!
