tiny does of magnesium & hot soaks in epsom baths w/ massage, using foaming bath soap of choice. 20 minute minimum. 1/2 glass of red wine helps too. I've soaked long enough for the water to cool. there's no danger of using too much epsom salt or soaking too long. I prefer the cheap epsom salt from Walmart & Dr Teal's Eucalyptus and Spearmint Foaming Bath
