This cough is driving me crazy!!!

I am still dealing with a chronic cough, that I have had almost half a year now. It's affecting my sleep, my job, and life is just not enjoyable anymore. I have gone to a new doctor, that tells me it is a side effect of the blood pressure medicine that I have been on. So he immediately took me off, and said that I should feel some releif, in two to three weeks. I can't wait!
