Thanks for being the trail blazer you are. That's what I like. Tips, tricks and all other bags of info. My MAC has been negative the last two but I can' seem to to shake the Pseudomonas for very long. I'm thinking our municipal water supply is the bad guy. I'll be "again" talking to our water works folks to see if they will do some testing. I don't think they want anyone rattling their cage. Currently I'm inhaling Tobramycin and can't seem to get through the process even after nebbing 30 min. I've tried Neb Doctors and Trek S (portable) compressors. I alternate between AeroEclipse II and regular set up with aerobika. One is not better than the other. I know I need to get the med in me but how long to keep it up. I usually stop after 30 mins. Any ideas? Thanks. Faye
