Same for me ...For me, nicotine from ecigs is far less 'addictive' than coffee (or caffeine from coffee, if you prefer).
I can easily not vape for 6 hours - there is no real 'pull' to use the ecig even after 12 hours.
When my power went down for a day a couple of weeks back, not being able to brew a coffee resulted in real withdrawal symptoms that I would describe as at least ten times stronger than the ecig equivalent. Try it one day and perhaps you'll see what I mean: no tea and coffee is much more painful for someone who has been vaping several years and has long been over cigarettes.
I was reduced to heating water in a cup on a trivet lashed-up from coathangers over a large candle. It wasn't very good, and when the power came back on, the relief was incomparable.
So if you asked me to give up vaping or coffee/tea for a day, the vaping would be far easier to drop.
However, I have been vaping now for a 3 years and well over the initial
transitional thing. To tell ya the truth, I vape a lot only because its there,
however, I really don't inhale that often and only inhale deeply if experiencing
outside stress.
Had some dental work last month and couldn't vape for a couple of days ...
No real big deal. However, I had my coffee !!
If forced to make a choice between coffee and e-cigs to give up ...
Bye bye e-cigs.
