My husband was having Acid reflux. I read that taking digestive enzymes can help with this. So he took them and improved very well. But a year later the problem came back. It was becoming a bad problem at night where he would wake up choking fluid that came up from his throat. Not too long after that he was driving and ran off the road. Doesn't recall it happening and there was a doctor that diagnosed him as having sleep apnea. He followed up with testing to confirm the problem. It seems that when you don't breath well you starve the body oxygen and that causes the stomach to become over active. This can also lead to your heart stopping in your sleep. So if you have Acid reflux, please investigate if you might also suffer from sleep apnea.
