Honestly though if you are able to servive with no nic... are you able to survive with no vapor... if so if you can survive with out the motions of smoking...than stop stop stop there is no need to be doing it... just buy some flavoring and direct drip on your tongue and forget the VG or PG. I mean this is of course only a suggestion I am not trying to say what you are doing is bad, but if you are having this much discomfort than I say "why bother"..
