I'll try and answer a few based on personal experience but is in no way is one person a scientific representation of the vaping population.
Every now and then I get a scratchy throat ..and last night I felt I could not breathe..of course I am sure it is because of smoking and not vaping..but
I think the PG probably causes more of a scratchy throat feeling. PG gives you more of a throat hit. VG gives you vapor but can cause a heavier feeling in the lungs if you inhale it somewhat deeply like I do. About 3 weeks in I got a pretty bad sore throat and switched over to inhaling just into mouth and exhaling through the nose.
How much can vaping stop coughing...or shortness of breath..if at all?
I have little if any cough any more. If I exercise I get short of breath but I think that's from lack of exercise and cardio routine. Most exercise I get is going up and down stairs 4 times a day and a short distance from car to office.
I know emphysema can never get better..but can vaping make is worse?
No clue. Maybe others can help you with that one. I think I've heard a few mention that it helps slightly with their asthma.
How long after stopping smoking can one expect to stop coughing in the middle of the night?
Does the amount of vaping make any difference when it comes to stopping coughing?
I think it's a symptom of quitting smoking not of vaping. Although if your throat is getting irrated try not inhaling into lungs or throat for a while. It was about week 3 for me and a coughed non stop at night for almost a week. Some people go through this process and some don't. Some go through it after 2 months in. For some it lasts from several days to months. I think it's mostly your lungs just clearing out the tar.
Does nicotine cause coughing?
See comments above. It may irritate your throat slightly. Not sure if you ever tried the gum or unflavored but personally think nicotine has a slight peppery taste. My taste buds could be different but that's what I detected when chewing the gum or vaping unflavored...maybe that's the PG?
Can vaping cause insomnia?
I've had insomnia for years way before I started vaping. From what I can gather it acts much like caffeine does. So if it is keeping you up at night cut back your nic level at nights. I'm at 24 for the most part right now. I tried switching to a 4mg at night but it caused me to replapse a few times. Try lower levels but probably don't cut it as far back as I did if you have issues sleeping. If you had issues sleeping before hand it's more than likely nothing to do with vaping. Did you used to smoke before you went to bed? This was a few years ago but Dr said trying to cut smoking out 2-3 hours before bed would help as it increases heart rate and can make it more difficult to fall asleep.
There were days I slept through the night..but lately I wake up almost hourly.
Welcome to years of my world...if you find something that works besides prescriptions let me know.
Cause I wake up at all hours...I used to wake up to cough...now I just wake up...I cough also...not as much...but I still wake up...
Sounds like you may still be waking up because of the cough. You can cough and wake yourself up and not even realize it was the cough that woke you up. You have anyone that sleeps with you can give you some insight into when/why you are waking up.
