My thinking is based on the idea that the success rate for new vapers is maybe 30-35% at best, based on the few numbers I've run across. So I think that keeping to a nic reduction goal is counterproductive *IF* the end result is a relapse and Fail.
And I don't think most people know up front if they will succeed or fail their primary objective of quitting smoking. So the way I see it, job #1 is to get well quit of cigs. Job #2, only down the road can be taming the vaping habit and dealing with the nic.
James (the op) is on his first or second day of vaping. I doubt he KNOWS (as you suggest you did) if he will succeed or Fail. I know I was never sure until I was a couple months totally smoke free. And at that point I was about 4 months into vaping since I was dual using for the first 7 weeks.
Totally agree with this -- it's ridiculous to think of cutting down on nicotine before you even know what level will suit you. E-cigs are not patches; there is no arbitrary "rule" that says you have to quit vaping, or lower your nicotine, or anything else. Vape the level that feels right to you, until/unless it doesn't feel right anymore -- which does seem to happen quite naturally, but everyone has their own time-frame for how quickly it happens. I had to start at *6mg* because anything stronger made me feel very sick; got up to 10mg, now at 9mg, and it works just fine, because I don't chainvape constantly.
I'm another who can't vape much VG; I vape 86%PG/14%VG, because any more VG than that makes me completely unable to breathe. If you're short of breath, that sounds a great deal more like a problem with VG than with PG; PG makes it feel harsh and burning, and even burn your throat red, if the problem was with the PG.
And absolutely, you don't need to inhale vapor very deeply at all; vaporized nicotine absorbs *much* better in the mucosa of mouth/throat/sinuses-nasal passages; it's hard to break the inhalation habit, but it's really not necessary, and in fact inhaling too deeply and too rapidly is very counter-productive, since it doesn't give the mucosa time to absorb much nicotine. Until I learned to take a very soft, slow hit, hold it in my mouth and throat a bit before inhaling, and then exhale thru my nose as much as my mouth, I was still dependent on the morning smoke; once I got the technique to vaping, that morning smoke was history.
