How do I stop having heart palpitations?

I had a similar issue with my heart. The episodes were primarily at night and had me very frightened. Doctors did tests and ultimately gave up. I set out on my own to do some research on possible remedies I could employ myself. To my delight, I learned that vitamin D, taken once daily has resolved the situation completely. Do check into vitamin therapy for your palpatations...it worked for me. Good luck =)
