This may or may not be related to the OP issue.
I also apologise for the long post.
I am not saying this is scientific research I am not even saying that it should work for everyone. I just state what I observed on my self for long long time.
I spent a good time of my life struggling with my digesting problems.
The only time I got better is when I stopped listening to this hi acid crap and stoped the acid channel blockers which caused me stomach bugs.
Actually it is exactly the opposite. It is lack of acid not too much acid.
But once a person gets ulcer which caused by proper environment for the stomach bugs you can not tolerate any acid. So it becomes a delima. You have first to kill the bug before you increase the stomach acid.
Once you have no ulcer what worked for me is to take some light acids like pine Apple, diluted lemon or viniger.
Never had any problems after increasing my dietary acids.
One way to prove that, is when I drink lots of water directly after the meal.
It will increase what people call acidic stomach. How does diluting stomach acid increase acidity?
Another way to disprove this acidity issue is to drink very cold water after meals. You will get this feeling of what people and doctors call acidic stomach.
the proper temperature inside the stomach is necessary for the stomach acids to work. The low temperature retard the acid from doing its job. So it is lack of acidity not too much acid.
