I just want to know if any of you feel different on a daily basis? Let me explain..... some days I feel fine, but then the very next day I feel weak and a tickly, persistent cough, then the next day brings lots of chunky mucus cough, and then it changes the next day? Sometimes I feel like uh.. oh... I'm coming down with something and then nothing ever comes of it. Do you guys ever feel like this or is your CF consistent?
