I have bronchitis again. Second time in 6 months. I have been using an inhaler, which works really well. It makes my heart beat a little fast. The doctor said it isn't dangerous, but it still freaks me out a little. I have been sick for two weeks and am so tired of wheezing and coughing. Due to my anxiety I hyperventilate often, which started 6 months ago with my first bought of bronchitis. This is a nightmare. Anyone have their own experience with bronchitis you can share? Also, how long will I need to use this inhaler. I just want to feel better and get some sleep.
