Wow, wow, wow! It is always exciting to have something work well for an ailment, especially when you didn't think it would. :)
I have used apple cider vinegar for years and it was so great for heartburn and gall bladder attacks.
In recent months though, my digestion has seemed worse, even with ACV. Everything I was eating seemed to be bothering me, even foods that had never bothered me before, and foods that I didn't think should bother anyone. I was having frequent gall bladder pain and a ridiculous amount of burping.
I have read about Betaine HCL with Pepsin here on EC. I knew it was something I should try, especially reading that digestion can slow down as you get older. I ordered some and took it with skepticism. I started to take one capsule with lunch and one with dinner. I don't take one with breakfast since I tend to eat a light breakfast. To my great shock and delight, foods are no longer bothering me and burping is greatly reduced!
