maybe upping the number of treatments you do during the day? i think the best option though would be to talk to your doctor and see if there is an oral antibiotic, tobi, colistin etc. that you could try before IVs.
you don't want to just let this go though and get really out of control because you might lose lung function permanently if you don't treat this infection.
I know thats not a fun answer but its probably the best idea.
hope you get to feeling better soon!
