It is so encouraging to read that all of your treatments are so important. My 22 year old son skips treatment and meds all of the time. Since he is in college and out from under my thumb<img src="i/expressions/face-icon-small-smile.gif" border="0"> it is so difficult for me to see him ruin his lungs. He has not done chest compression for about a year. He relies on meds to help him out. He has done so well so far in his life, and it just tears me up to see him not take as good of care of himself as he can. When does it click? How old will he have to be before he sees how important all treatments are?
