> Also, if you have acid reflux, vinegar will absolutely destroy your stomach and make your acid reflux 100% worse I replaced my Prilosec prescription (for severe acid reflux) with diluted ACV. After a few years, I no longer needed even the ACV, although I occasionally take it for various other claimed benefits. It has been about eight years since I last needed Prilosec. I don't have a hole in my stomach, and in fact am healthier than most people I know - mostly hooked on some meds. Sounds like your friend did something wrong. Possibilities: she took way too much ACV, or she didn't dilute it. In my experience, it's pretty common for people to mess up even simple [nutrition and healthcare] instructions.
