Thanks guys. I'll wait for 2 more weeks and go see my doc.
two weeks isn't long enough. I take the same 250/50 and it took almost a month to work. I've been on it for a year and it's works the best for me. hang in there for a couple of more weeks and see if it works. If is doesn't , do like Tammys says go back to doctor and find something that works for you. Mike
It took a couple of days for me to see a small improvement and then 4 months to have my lungs to fully settle down (then again I ignored the coughing for 5 months).
If you see no change though, I would head back to the doctor for something else.
