if someone is daily having excessive burping for more than a couple years, and drink almost 98 percent Distilled Water as their water source...could that be a connection? My brother is in denial, but i think he also has issues in the morning on the toiled every day. he thinks hes doing the super healthy route because someone told him to only drink distilled water for the flouride. but u can easily get so many water sources that arent distilled like spring water which can have no flouride too. what do u think? im worried but he is hostile to even talk to, he thinks hes super healthy and is literally against modern medicine
