Hello fellow long term vapers. 
I quit smoking via vaping in 2009 after my lungs were declared shot by a doctor who diagnosed early emphysema. Although lung function restoration is not possible where serious damage has occurred, my lungs improved radically where damage was not irreversible.
I have vaped happily ever since (mouth-to-lung, ending off with a pen-style JustFog device). I trialled Direct-to-Lung and low resistance cloud-chasing devices but my lungs screamed out a warning message that this was very dangerous and they would not tolerate it.
I had been using the same Vanilla flavouring throughout but Covid19 apparently knocked out the manufacturer and I trialled many samples of other flavours, including Vanillas, some fried my atomisers almost instantly, but ALL resulted in my lungs objecting and me waking up during the night unable to breath.
Not able to let go of my Nicotine, I was forced to go flavourless. The advantages are that my atomisers can be cleaned periodically and last much longer and my lungs don't complain. On the downside, the taste is not great at all.
So, are there any flavourings out there that are proven to be very safe and won't irritate, particularly in the case of old and damaged lungs?
