text: I bought this product after hearing coworkers discuss it. I get painful leg and foot cramps quite often. Sometimes they will awaken me several times during one night. I've been applying this spray twice a day as a preventative and for a couple of weeks and have only had two very mild foot cramps that went away quickly. (I sprayed the cramping area as well.) I can only provide anecdotal evidence that this works; it may be the placebo effect. I don't know and I don't care as long as I see a positive effect. I spray it on my hand and rub it into the leg for those of you who object to a wide spray area as one reviewer did, although I don't find the spray to be that far-reaching. I just think massaging it in makes sense for me.
