Get yourself a good nicotine vape rig. The kind that has a big tank so it’ll last all day and you can use whichever flavoured vape liquid you like best. Switch to that 100% of the time, right away, no exceptions. Don’t worry about how to quit vaping until you’ve gone without smoking for at least a few months.
It’ll be hard, but not nearly as bad as it is if you try to quit both smoking and nicotine at the same time.
I thought maybe it was just my imagination that it’s been really slow since Wednesday, but you can see it clearly on the charts at the bottom of the page there.
