You might want to try WTA (whole tobacco alkaloid) eliquid, I vastly prefer vaping with some. Do a search and you will find jillions of threads.
Also, um, I am a pretend non vaper at work. Snus got me there (and out of a smoking relapse too) I can go about 13 hours is the most I have gone at work, not vaping. I actually make sure I use a couple pieces of snus on weekends, etc., because I have a feeling it is MUCH higher in alkaloids than even WTA liquids which are fairly dilute. My brain desperately needs those minor alkaloids.
Swedish snus has been around a while and is said to be even more harm reduction than vaping. Swedish snus is sold under the name American General snus (confusing, I know.) Many gas station sell it, there is a store locator for it, if you do a web search. My main complaint was I did not love the taste but since my brain rapidly associates pleasure/effect with taste I got over that rather fast. It will cost you four bucks or so depending on your state to try it and in my opinion you have nothing to lose (with either, but WTA is usually a LOT more expensive.)
I see no shame in vaping and I do when not at work as I enjoy it, but using some snus every now and then to help you. Or, WTA. Either or. For some folks nicotine is not enough and I am one of them.
