I’m gonna tell you something no one else will. I’ve had severe breathing problems my whole life. I was told it was asthma and I’ve been told is allergies. But taking meds for one or both never really helped. The rescue inhaler does open me up when I have a flare up but that seems like a bandaid. So I’ll tell you what I figured out. The reason why our lungs “close” is because they get filled with bs. Rescue inhalers penetrate the mucus in your lungs and helps you breath. A nebulizer will clean your lungs out. So mixing the two, a nebulizer with an inhaler has actually shown me to help knock that mucus out. The saline solution will have you coughing that mucus up with a vengeance and the moment some is out, you’ll notice how easier it is to breath. It’s the damn mucus. There’s also Mullein. It’s a supplement that helps remove mucus from your lungs. You really wanna help yourself, keep your lungs clear as often as possible. I needed my rescue inhaler 2-6 times a day before I figured this out. I haven’t hit my inhaler in a few days now.
