I just wanted to give some advice to those who are interested in the Vibralung. I actually was able to get one this past week and I'm so thrilled. The rep said that it can be done with the vest so I figured I'd try them together. All I can say is, holy mucus batman...I knew I wouldn't sleep through the night due to all the coughing I did. I have gotten so much out it's amazing. I would highly recommend doing the together.
