Does anyone else cough up alot of fluids doing the breathing? I deal with a lot of sinus/allergy issues and O is really good at helping me clear my lungs/nasal passages but it's roughing going at it...especially since I've had the flu the past few weeks.

If I would continue doing it on a regular basis I would keep ahead of the game but I keep stopping. I'm hoping connecting here will keep me encouraged. I would appreciate hearing anyone else's story with near COPD kind of conditions.

Well, I don't have any kind of sinus issues or anything but I am a smoker. I'm 24 and have smoked since I was 16. I do O 2x a day and find that the more I do it and the more gusto I put behind the breathing, I will sometimes cough up phlem after the workout. But-stop and think about it. Whether you're a smoker or someone with nasal/sinus issues, by doing this breathing you're cleaning all the crap out of your lungs. So, if you have any kind of mucus anything built up, you're eventually going to cough it up-which is a good thing.

Jonathan, thank you so much for sharing your experience. I did think it was like that but with no one else seeming to share the experience I was a little worried. You have helped me feel more at ease!
