MIAMI -

About 70 million Americans suffer from acid reflux. Many of them are trying to find a natural way to relieve their pain.

You may have experienced the heartburn, indigestion, nausea -- and the holiday season diet of high fat food and alcohol can make it worse.

It can be aggravated by things like high-fat foods, chocolate and alcohol, which are often part of the diet this holiday season.

Relief often comes with costly prescriptions, but chronic use can cause dangerous side effects. That's why more and more people are looking for natural remedies.

In 2007, Kelli Minson was jarred awake by her husband, Dr. Matthew Minson.

"Matt woke me up really, really early in the morning to ask me to take him to the hospital and he said he couldn't breathe," said Minson.

"(The feeling) was rapidly progressing, so I went into the study and wrote a quick note should paramedics arrive and I wasn't able to communicate with them," said Matthew Minson.

Matt Minson was diagnosed in the emergency room.

"(The doctor) came back and said, 'You've got reflux, a progressive case of reflux, and I was surprised," he said.

Matt Minson has what's called Silent Reflux. There are often no symptoms until it's too late.

Gastroesophogeal Reflux Disease, or GERD, is very common.

Food or liquid in the stomach leaks back up into the esophagus, causing irritation or heartburn.

Matt Minson was given a prescription and asked to sleep head elevated.

"If I would go into a recumbent position or lie down flat, I'd start to feel this fullness in my throat and start to experience the same sort of problem I had initially. Once you've gone through that and know what you're dealing with, you're like, 'Here it comes again,'" said Matthew Minson.

When they couldn't find anything readily available, Kelli Minson invented The Gravity1st Elevated Sleep Systems™ mattress. It fits on top of a regular mattress and has a seven inch incline. The cost ranges from $249 to $379.

"We tried really, really hard to get the cost of the largest mattress we make within the range of a one-month supply of medication that was out of pocket, and I think we came within about $25, so we're pretty pleased about that," said Kelli Minson.

"Probably within a week, I was dramatically sleeping better," said Matthew Minson.

Gastroenterologist Dr. Drew Dupont said sleeping with the head elevated has been shown to decrease the acid level in the esophagus.

"It definitely works. It doesn't really prevent reflux, but it increases the emptying from the esophagus. So you still may get the reflux, but it clears out faster, so you get less of the problems at night," he said.

Dupont said if you're having problems with acid reflux more than twice a week, you'll want to see a doctor.

"Over time, the lining of your esophagus changes. You kind of adapt, but it's a condition called Barrett's Esophagus and there's a very, very small risk of developing cancer of the esophagus if you have this condition," Dupont added.

Long-term prescription drugs have been associated with bone loss and fractures. That's why so many sufferers are looking for alternatives.

Evamor Naturally Alkaline Artesian Water has a pH level of 8.8, which is 80 times higher than most bottled waters.

"We're seeing a lot of interest," said Damon Michaels, the company's vice president of marketing. "It's growing by leaps and bounds."

He explained that while marketing the performance water as fresh tasting and pure, they also heard from consumers that it helped alleviate acid reflux.
