my brother and i, both with cf, have been using the vest for about 1 month now. the thing is, it doesn't seem to do anything! It's supposed to shake the mucus loose so you can cough it up, but after and during vest treatments, we cough, and nothing comes up. it seems useless to me, even when i did it with my hypertonic. the acapella seems to get a little more up. have you found this, or the opposite, to be true?
