fdixon63 I started toby in March of this year. I'm on my 6th round of it (for 2 weeks). Toby hasn't yet seemed to help me; however, I was told upfront it would take a few months and of course I'm doing only the two week/on/on program versus the 28 day. I nebulize twice daily with albuterol followed by 3% saline. No, I've never been prescribed the antibiotic you are using. I'll be interested in whether that works for you. I cough horribly -- that's my problem. Lots of green phlegm. Don't know if this info helps but you are welcome to ask anything you'd like.
