I know we are supposed to lay on our left side anyway, but my chiropractor told me that getting adjusted regularly and also laying on the left side will help minimize heartburn. I can definetly tell a difference when I lay on my left versus right when I have the heartburn. He said laying on your left helps keep your stomach contents in the bottom of your stomach whereas laying on your right brings it up. He of course said it more in medical terms but that was the jist of it. Hope this helps.
