Thank you for all your posts. I thought I was the only one with this going on. Ive been in deep depression for the last 5 months because of the smell and the nastiest taste in my mouth 24/7. Im losing my mind and ready to quit. Ive been to several doctors and all my labs come back normal. Cat scan, normal now theyre doing endoscopy and colonoscopy. This has affected every aspect of my life and its just getting worse. I dont ever want to be around anybody. Im seeing people post they cant smell it themselves but I do and so can everyone else. Ive tried so many things as far as diet and somedays its not as bad as others but than it comes back out of nowhere. Im to the point if yhey cant find out what it is I dont want to live anymore. This is no way to live for anyone.
