I have bad acid reflux , drinking sometimes
I have tried everything you mentioned , so I have learned not to eat before going for sleep
Give it a couple of hours first before you do , and don't drink alot of water at the same time , it seems to make it worse
And from what I have found , for the most part , your body could be , overall , acidic , which is not good
You want an over all body ph of alkaline , which fights off disease etc. better
It is thought that drinking a lot of water or other fluid with a meal dilutes the stomach acid, thereby contributing further to the problem. I would also suggest that our bodies are not well able to deal with processed foods, yet so many people rely on them for convenience. I work in a grocery store and I predominantly shop the perimeters, those being produce, meat (poultry and fish also), minimal dairy and frozen fruits and veggies. A very few canned things like tomatoes for cooking sauces and beans for a fast meal. Oh yes, one gluten free cereal for when I am too tired to cook and 'people kibble' will suffice.
