Doe anyone take tobi and cayston (or other inhaled antibiotics) on 2 week cycles or 1 week cycles? I am wondering if this will hinder the effectiveness of the drugs? Tobi (although keeping my hospital stays down) is literally making me so miserable I am ready to throw in the towel. I have no quality of life when I cough more with it then when I am having the worst flare up. I would rather be permanently attached to iv drugs. Desperately searching for an alternative to my months on tobi. Thanks for any help.
