A friend bought me a bottle of the magnesium spray to try as I suffer from night sweats, restless legs & pain in my joints when I am trying to settle at night. Must admit I was dubious as thought the above came with the territory when in menopause! Took about a week, but I started to notice a difference. I use it on the soles of my feet, knees, hips & elbows when I go to bed & after about 10 minutes I can feel myself relax. I am less fidgety at night, much to my husband's relief & feel calmer as I drift off to sleep. I still wake in the night but am able to get off again quicker as my joints feel less tense. I've now purchased the duo bundle for myself & am spreading the word. So grateful to my friend for recommending the spray to me.
