I have a dear relative on a lot of medication for her heart since she has a pacemaker, plus she has GERD. Well, I sent her some information on apple cider vinegar and she ended up learning that Protonex can cause breathing difficulties. I'm not sure if the ACV info pointed this out or what...She has been having difficulty breathing for a while now, so she went off the Protonex and is taking the ACV instead. It is also helping her not have heartburn anymore, but more importantly, her breathing has greatly improved.                                            

I'm a firm believer in taking ACV. Please, if you have health ailments, look into it. It's natural, inexpensive, and can't hurt to try.
