I use my Voldyne inspired spirometer @ least 3+Times qday. Scared of pneumonia again since last time BUT is it me. Makes me feel nauseous/bloated etc?

Interesting.... cannot say in your particular case, but generally, increased abdominal pressure can cause those symptoms. Hiatal hernia, air swallowing are common. Oddly enough, yoga breathing technique or other training in breathing would fix it. Spirometry would also be interesting to see breathing pattern.
