Hello, I am a 24 year old woman with CF and I have a therapy vest. I have to admit that I hate doing the thing, and I don't think it helps me. I have recently switched doctors, and my new doctor has told me that if I don't think the vest is helping me to not waste my time doing it. I was just curious to see if anyone else out there has a vest and if they do or do not do it...and if they see any benefits from it. Any advice I could get is greatly appreciated. Thank you. Jennifer
