I got pvc's (weird heartbeat, nothing dangerous) from overexertion in spinning. I got high dose magnesium to make it better.
YEEEESSSSS take mag! i have been taking it for about 6 months now and not only do I not have the spasms anymore but I am sleeping better and I am calm and I was having heart palpatations. My Dr was proud of me for going for a more natural cure too! A dietician (spelling) is who put me on it.
