I notice that my numbers have been higher. Not much change in the diet. I was for years between 100 and 130 in the morning, but have seen a swing of a lot of 140 to 160's. I have been vapeing for about 4 months now.
Don't know if it has any thing to do with vapeing, or just some other change or stress, etc....
Perhaps check in with your doctor to see if the two of you together can figure it out.
Quitting smoking is a stress. I dunno how long you've been not smoking (or if you still have a few a day, just looking at your join date is all I have to go on)
Still, the doctor might want to know about your readings.
