I honestly believe that the stuff they are using in cigarettes today for them to go out after being set down has affected my health. Before they come out with it my lungs were good, the Dr. was surprised at how clear they were. I have smoked for25+ yrs.That was a year ago, I had to go to the emergency room 2 months ago because for about1 month prior to that i could not lay down at night for it felt like my throat was closing up and could not breath. It kept getting worse and worse and scared me.The dr believed i had conjested heart failure, i am waiting for futher test. I have had a few other people complaining about there breathing and coughing. Is there anyone out there had the same problem or does anyone know the steps i need to take. Thanks.
