@sounder27 Good morning. I had that nasty violent cough for years. It caused many pulled muscles in my rib area and back. Plus, put excessive pressure on my bladder. I too would throw up at times. So, I feel your pain on this. I was put on tobramycin in 2016. My cough was completely gone after 30 days on it. (Results can vary from person to person) I have been on the tobramycin ever since 2016. I am on it bi-monthly (one month on, one month off). Members in our group have also had success with Clear Lung. I am not possitive, but I think some of the ingredients (like licorice root) can cause heart palpitations. But, it may take high doses for that to occur. I hope you can find something to give you some relief.
