I have been taking HCL with Pepsi And it has worked to digest my food. However, like any pill it has side effects and the acid seems to go onto my back muscles and makes me stiff.
Warning to all you overactive thyroid people. I suffered with overactive thyroid for 16 years and only recently had it removed. Because I was over active and ate too much that's the reason I now have low stomach acid. So if you have the same issue get it removed quickly. Unfortunately, I was never advised this could be a future problem
