@blackle22 I can relate to your situation. I have acid reflux/sour stomach since 3 years, sometimes better, sometimes not.
Since I learned about TMS two months ago, I see a clear connection between my physical pain (shoulder, achilles tendon, muscles, acid reflux, headache...) and my thoughts and feelings.
So, I decided to stop taking PPI. I took them in a dose between 20 to 80 mg a day. I reduced the dose to 1 pill (20mg) every 2nd day. It was okay. There are typical meals/drinks like coffee, alcohol and so on which I (have to) avoid but I think I will be able to eat/drink them in the future. Since 9 days I am completely without PPI. The first days were quite good and I had no changes or flare ups. But, since Monday my mind is out of control because I am afraid of two events in the next week. My sleep is bad, I am nervous and brooding and so on... And, who would have guessed, the acid reflux and some other symptoms are back.
This is an evidence for the mindbody connection and I realzise that dealing with my psychological issues and current stressors is the only way to feel better. I weaken the painfocus by realizing this. Of couse, acid reflux is a very intensive pain and it takes much energy to stand it. Trust und confidence are the sources of energy.
You told us that you also have current stressors. Are you journaling about them? In my case journaling, meditating, deep breathing and talking with my psychotherapist are the best ways to cure. Did you try meditation or something like this? The aim is not to eliminate the pain. The aim is to calm your mind, to relax and to enjoy the current moment without focussing the pain.
