For years I was sucking Gaviscon half the day because I had acid reflux, heartburn and indigestion. Doctors put me on proton pump inhibitors but as soon as I went off them everything came back. So logic began to take over - I'm getting older and things slowing down, what if it is not too much but rather not enough acid to digest food. I began to drink cider vinegar every day after meals and found a lot of relief, so then I tried Betaine and it is what my body has been looking for, for years. Yet doctors do not seem to realise that the symptoms are the same for too much acid or for not enough acid. I guess they have to do what Big Pharma tells them and a permanent control with only a simple supplement is not the desired outcome for them. Add a good organic probiotic for good digestion balance and the digestive puzzle is solved. I think I may have had too little digestive acid even from childhood, as I used to be subject to megrines at regular intervals accompanied by vomiting. My approaching "old age" will be a lot more comfortable now.
