I need help … I am down with a severe cold, and have trouble using my CPAP machine. I tried using vaporizer on the nightstand for the cold, hoping my congestion in sinuses and chest would be out. A friend told me about adding Vicks Vapo Steam liquid medication to the vaporizer. Wonder if I can add the Vapo Steam into the humidifier. I even thought of adding it to my CPAP machine, but felt it was not a good idea…..I am getting sick of this congestion.
