Hi Nonnie, since my first Anaphalatic Shock (lucky lived to tell about it), I have refused any meds - foods - with sulfites in them. Please don't take chances, your reactions were too frightening.
In regard to your CPAP mask use: I also have used many CPAP masks. I have been using a CPAP for six years. I now use the Mirage Activa LT mask, and likely will get another one similiar, next replacement. I have used nasel pillows and actually liked them. When my presure went up to 15, had to stop using them. Never gave thought to going back to using them, since my presure went down to 11. I couldn't use a full face mask, there were too many leakages. My CPAP is the Resmed Elite.
Hope your feeling better
Hugs
Gerri
