Well this might help explain why I had heartburn so bad when I was pregnant because as soon as I found out that I was I cut out all caffeine immediately.

I had never heard this before.  I have heard that caffeine can aggravate acid reflux.  Does the acid reflux that occurs from quitting caffeine suddenly become a chronic condition or does it go away after a while?

I knew that quitting or cutting down on caffeine could cause headaches but I did not know it could cause acid reflux. Fortunately, I have no plans to cut down on my caffeine because I need it so much!

Natasha, quitting caffeine does not mean quitting soda.  There is plenty of soda that does not contain caffeine.  And I don't mean those who drink only a little caffeine – it's more those who are coffee dependent and drink a lot of caffeinated drinks each day.  In this case, yes, quitting caffeine suddenly, cold turkey, can cause acid reflux to develop.

This is something most people don't know but if you try to quit caffeine suddenly when your body is used to a lot of it, it can cause you to develop acid reflux.  What happens is the flap in your esophagus (I forget the scientific name for it) loosens and doesn't stay closed properly.  This allows the acid to come up in your throat more than it did before and can cause esphageal lesions or ulcerations from the acid.  If you want to quit caffeine, wean yourself off slowly.
