I am a believer in both the salt/soda rinse and the club soda. There was not much out there that would cut the mucous the same way and the constant flushing would feel good as well as heal the mouth sores. I am almost six weeks out of treatment with sore throat issues that are difficult to address but the mouth sores were cleared up at the 4/5 week period and the thick green phlem replaced with normal phlem like mucous in back of throat. Mostly when eating or drinking. The pain in throat has increased slightly in the past week so I've increased my breakthrough pain meds. It has impacted my eating but I'm no longer choking and feeling sick from the mucositis. I have learned this is not the Rabbits race, but the tortoises. Slow but steady wins the race.
