Have you tried 100% VG? Apparently PG is used in the asthma inhalers, I don't have the box from any of my inhalers so not too sure if it is included in mine. But PG is what gives you that hit in your throat apparently, so I would probably go with 100% VG and 0mg.
Presently have Zeus Dimpleberry in Cloud which is 100% VG (3mg nic) in my Zephyrus . Billow 2 , Lemo 2 & Atlantis have 80 VG/20 PG.
I do not get on with many inhalers , maybe due to PG intolerance maybe.
My asthna is very much in control nowadays & only use inhalers spasmodically , more so at the moment as high pollen affects it.
Can say for sure dry hits will definitely cause some wheezing
