Troutspinner - I'm about 4 hours behind you in my transition to vaping. I too am pretty amazed at how quick I'm transitioning. I did have 1 analog this morning with my first cup of coffee. I think that was mainly to see how my throat handled the smoke.
One thing that I'm having troubles with is that I'm finding that vaping seems harsh and I tend to cough more than I would have thought. I'm assuming that it has to due with breaking in the atty's and/or the juices that I received - Curtis's Coffee (16mg) and Energee (11mg). Placed orders for a bunch of different juices last night. Now to find that sweet spot - good times!
I gave up smoking five years ago (a horrible-painful process without vaping) after smoking for 30 years. Then I started smoking again in Nov (Mother died) and was smoking up until I got an npro a week ago -
Anyway, the first time after a quit smoking after 30 years, I had a dreadful cough for over a month - my doctor said it was my lungs cleaning themselves out after 30 years of tar - that may be what is happening to you and may not be related to vaping
