Hello, I just joined to ask the community here about their experiences with breathing problems related to vaping. Interestingly, I can smoke a ********* or cigarette without my breathing getting shallow. When I say shallow I mean, after I vaped all day three weeks ago, I couldn't take a deep breath. It feels like I am trying to take a deep breath but the bottom of my lungs aren't filling up. It feels like a 90% breath every time. My shortness of breath has lasted for 4 days after quiting vaping. I never had this happen no matter how much I vaped in the past two years, up until three weeks ago. There are no other new environmental or dietary changes in my life. No new stress. Vaping is of course how I relieved my stress. I've been vaping with a 70 w Siegeli, or whatever, airtek dripper, and Juicemafia's Highway 4 75/25 vg/pg 6mg juice. My buddy was saying maybe it's because I have such a high level of VG, or maybe because 6mg is too high for me. But I don't think those are the issues, I might just have sensitive lungs. Oh, and I did go to the doctor, they listened to my lungs and took an x-ray. My lungs look good and clear on the x-ray and listening to my breathing only revealed a slight tiny weeze. Again, this completely came out of nowhere. I'm wondering if maybe something happened to my juice, like it sat in the sun too long and changed it's chemical components or some shit. I don't know. I just want to understand the causality! I need my crutch! I should also mention this not being able to take a deep breath has also interfered with my yawns. It's like I want to yawn but my body can't quite do it properly. Any feed back would be appreciated. Thanks!
