It sounds like that is what you are already doing according to your previous posts? If it were me I would do 7% both times but since you do not have symptoms maybe the second time is not so important? You want to do whatever you can to keep the Pseudo knocked back and prevent it from becoming mucoid strain. I tried Toby inhalation a couple of years ago. After only 5 treatments I had to stop because of reduced urine output. But I am prone to that ever since prolonged use of Augmentin. I now have to be super careful of taking things that will produce that effect. I have a friend who took Cipro for 10 days and Toby inhalation at the same time for 2 weeks. Before taking either she used Korean Ginseng to help open up the biofilm and allow the antibiotics to penetrate. Anyway she seems to be testing negative for Pseudo now. She was able to tolerate the treatment but just barely. The Toby made her cough terribly towards the end. But it seems to have worked?
