The other treatment I do is called a vest. It's much harder to explain because it's CF specific, and pretty much no one beyond the CF world has heard of or seen a vest. It gets the name "vest" because I wear an inflatable vest to do the treatment. There are two plastic pipes that stick out of the inflatable vest, so it can be inflated. The vest I wear connects to the vest machine with two large tubes, and the vest machine is just a huge bulky box that weighs about 35 pounds (not including the weight of the tubes and the cords). The vest machine rapidly pumps air into the inflatable vest, making it shake around. This shaking shakes my body, which shakes my lungs to break up the stuff inside them, so I can cough the stuff out. The vest runs about a half-hour per session, and I do one session in the morning and one session in the evening. 

I rarely cough anything up, which is a very good sign. It means my lungs are actually quite clear. I still do the vest everyday, unless I'm doing activities that simulate the vest for a long time. Trotting/cantering a horse does pretty much exactly what the vest does. Riding my dirtbike over a series of potholes and rocks also simulates the vest. 

The vest makes talking hard for me. Only people who are used to me doing the vest around them can understand me, since my voice rapidly cuts in and out due to the shaking. I don't like doing the vest (or any other treatment for that matter) around people who don't know me very well. People like that tend to be overly curious, but they can't understand my answers to their questions until my vest treatment is over. Sometimes people just have to poke and prod at the vest. While the vest is basically indestructible and I know how to reset the settings, I still get really irritated when people try messing with it while I'm doing it. Luckily, people understand what the "death glare" means and back off pretty quickly.
