UPDATE: I have taken my second dose and so far so good, breathing is better and my cough seems to be less intense. It could be placebo; it could be meds. I actually noticed a slight improvement yesterday too. Walking to the hospital from the car< I was very winded after going from the hospital to the car, I noticed I was ok. Today I can actually take a deep breath and not hack my head off!! WOO HOO HOPE!!
