Three part answer information, what not to do, and what to do!

INFORMATION!!!!!!
I have a very severe case of Acid Reflux (G.E.R.D.). I have had to go to the hospital for some of the heartburn that I have had because the pain can become overwhelming or your breathing can be effected. It can be caused by Smoking, Drinking Beverages with caffeine (My case), Drinking Beverages with Alcohol, or can be Hereditary

The good thing about G.E.R.D. is that it can be a temporary thing and can be cured. It is never a permit thing even if you end up with it for the rest of your life it has the ability to be cured.

G.E.R.D. is caused by too much acid being created in your stomach. This can lead to or cause ulcers, esophagus damage, heartburn and/or damage in the mouth. . Other symptoms that can be found in a few cases are dizziness, tingling in limbs, numbness of Limbs, Chest/Back pain focused on the left side (in most cases), and shortness/difficulty breathing.

WHAT NOT TO DO!!!!!!!!
In most cases, stress is a factor to the reflux if you watch what you eat and reduce some of the stress it will help. If you watch what you eat for about a week you should find relief, if you do not then that is when you definitely what to listen to the doctor. Things to watch for are as follows:

Fatty Foods
Citrus Foods
Foods That Contain Grease
Fried Foods
Chocolate (including any Coco)
Caffeine
Smoking
Alcohol
Tomato Based Products
Lactose
Roughage (Berries and Nuts)
Onions

WHAT TO DO!!!!
The two foods that I recommend is Black strap Molasses and Raw honey. The apple is better for night time reflux while these will work for just about all of it. What you will do is take about a tsp. of whatever one you chose. Molasses being the better because of strength and nutrition, but must be use to the taste. What the substance will do is stick to the sides of the esophagus and do two things, one is heal and the other is protect.
On the healing end, both substances have a healing property in them, and as they sit on the walls of the esophagus they will heal it. This is also helpful if you have a sore throat in the morning from refluxing.
On the protection end, both substances are high in sugar and when acid that is refluxed comes up to that the sugar will neutralize it and it will not longer be a problem at that point.

I would also look to putting Cinnamon and Ginger in you diet, they have been know to help with digestion and will help you reduce the amount of acid needed to brake down food, therefore causing you to reflux less.

Take a 1 quart container add 2 TBLS. raw honey
1/2 C. raw apple cider vinegar
2 Tablespoons of aloe vera juice
a little bicarbonate of soda (optional)
fill rest of container with distilled water. Shake well. Refrigerate. Drink a couple of swallows a.m. and p.m.
Give it about a month. Amazing. It not only gets rid of the acid reflux, but the honey and aloe helps heal the esophagus.

For more immediate relief (but not a cure) try drinking dill pickle juice when the heartburn is really bad.

You COULD try any of the aforementioned herbal/alternative remedies, but just know that there really isn’t any scientific evidence to back it up. But many people swear by it. Your choice, though. Good luck!

p.s. Also, I would definitely try all the preventative stuff as well, including putting the head of the bed up a bit, staying away from spicy foods, peppermints, chocolate, etc and not eating less than 30 minutes before a meal.
