Severe acid

I'm not a Dr but I do know taking antacid like Ranitidine only supress symptoms and give temporary relief BUT they actually in long run make heartburn worse. Look it up i'm not very good at explanations anyway regardless of what it is cleaning up your diet is essential to whether you continue with heatburn or live without it but you'll need to sacrifice things you probably like so can you put up with heatburn and eventually become seriously ill or do you want to fix it now once and for good. If you clean up your diet and revert back the problems your having will arise again. 

Ditch caffine and smoking firstly if you partake no soda of any kind basically nothing with any sugars except from fruit do not eat bread of any kind and consume little dairy very little. Do not eat readymeals do not drink alcoholic beverages.

Consume water with every meal meals should be bland initially and it will take around 2 weeks for symptoms to disappear. Consider eating not because you like the taste but because the the food is beneficial to you meaning foods that have anti imflamatory properties or anti fungel ect things like garlic cloves (1 a day) disgusting at first and yes it might bring on your heatburn initially but it really helps and helps with blood circulation to. Drink apple cidre vinegar i know these things seem counter productive but if it is bacteria these help remove it. Herbs like Oregano especially Oregano will help you but do not over do it. You don't even need to prepare a meal get a cup of hot water put oregano cinnamon and honey mixed with a spoonful of apple cidre vinegar and then consume either with or after a garlic clove. Yes it'sabsolutely disgusting the taste but it's 1 minute of your day.

I'd also reccomend a good pro biotic but not necessary although would improve you overall.

If you have any other medical conditions any at all do not take my advice without speaking to a dr or nutrition expert.

Yes well you really shouldn't consume garlic whilst on wafarin as i know it's a anticoagulent you should seek advice from a nutrionist which i am not but doing your own research is great to it's just following through with it.

Out of personal experience - I am also post menopausal - please get your stomach acid tested to see if you actually have TOO LITTLE instead of too much! The PPIs are for people who have too much stomach acid and they kill those of us on them, who have not enough stomach acid to start with. They suppressed what little stomach acid I had and gave me such drastic reflux that I was literally burned inside from my stomach up my throat, into my neck, jaw and even eyes! I had chest and back pain, couldn't eat because my mouth was burning and my throat was raw! After I did the simple baking-soda test below, I realized that I have low stomach acid and stopped taking the PPIs altogether...within days, my pain and suffering was somewhat relieved! I'm still not healed, but it definitely is not as bad as while I was on the pantoprazole!

"TEST!!! Some estimates suggest half of individuals over age 55 have inadequate stomach acid.

To perform this test: mix one quarter teaspoon of baking soda in eight ounces of cold water, first thing in the morning, before eating or drinking anything except water. Drink the baking soda solution. Time how long it takes to belch. Time up to five minutes. If you have not belched within five minutes stop timing anyway.

If your stomach is producing adequate amounts of hydrochloric acid you should probably belch within two to three minutes. Early and repeated belching may be due to excessive stomach acid. Belching results from the acid and baking soda reacting to form carbon dioxide gas. The Heidelberg or Gastrocap tests can be employed for confirmation of the results of this test."

Just an idea! Good luck to you!
