We are also having breathing problems with ProBed. I can't go near it and my wife has had an awful cough for 2 years, I kept telling her it was ProBed but she wouldn't listen, until today that is.
ProBed makes my wife cough, I won't go near it because I can't breathe after using it. Trying to find something else but having tried everything over the last 20 years we are stumped.
