I would guess, and it can only be a guess as I'm a lifelong non-smoker, that if your bloods go up a bit, it would be transient as your body is a bit stressed by your lack of nicotine; a bit like carb withdrawal. Your body could be trying to keep you in a physiologically misplaced "happy place". Stick it out, and if my hypothesis is correct, you'll moderate back to your more usual place.
But, yet again, Mike, this is sort of another one-off, at this stage? We can't drawn any conclusions from one-offs.
