@sounder27 I periodically grow bacteria and become ill. I am usually given antibiotics and there have been times when finding the right antibiotics has taken some time. I also one had a particularly bad bacteria and to prevent it from colonizing, I was given Tobramyacin for a year (1 month on and 1 month off) For the most part I have done well and I believe that has a lot to do with the regimen I have for clearing my lungs. I use my nebulizer at least once a day. The meds I use with nebulizer are hypersal saline solution with albutrol Sulfate. I also use a technique called autogenic breathing, which I was taught when I was in my 30's. I do it also at least once a day. Clearing my lungs, using my two inhalers twice a day, plus taking Azithromycin 3 times a week is keeping me mostly free from bacteria and illness. I found out that for best sleeping position, it is on your right side. However, if you have to sleep on your back, just make sure the top of your bed is raised so that your head is above your heart, and your lower bed is raised up to slightly raise your legs.
