Sounds like that horrible chest cold I had. 4 Weeks. Passed out while working as I could not breath, (I work outdoors). I had to stop smoking as my lungs could not handle anymore. And I do have a vap. All you can do is wait. Have you tried those medicines with the exporates (not spelling right) Your local pharmacy would know. It is the cough medicine designed to break up severe chest colds. It took me about 4 days of that before my chest started breaking up. It was not pretty. My lungs are still healing. I cannot smoke unless it is through the Vap at this time. It sucks that is for sure and mine caught up with me two days after I got that flu shot. Agggghhh. Good luck. It will force you to slow down. I am sure my cold was worse than normal as I was toking way more than usual for the past few months.
