When I stopped Kaly the one time that I did (at the end of Ph.2B in 2008) I had a flooding feeling...very wet - felt like hemopytsis. I wonder if this is what your friend is referring to Mandy? I wonder if his CFTR value isn't holding steady on the dose. He should note what time of day he has the feeling the most. I likened the feeling to "30 years of cf flooding back in" It was one of the worst feeligns I have ever had and definitely link it to increased anxiety in my processing of the disease after that point. The only good thing was that it was not painful. Nonetheless, I think people should stay on the drug or ween off...not go off cold turkey.
