I smoke slightly more with ecigs than I did with cigarettes and I use the vape throughout the day. But whenever I have a real cigarette now I get a head rush and feel the nicotine quite strong, which is the feeling I would previously get with the first cigarette after the numerous times I quit smoking and started again. Clearly I'm using far less nicotine with e-cigarettes, which surprised me because I didn't notice any side effects (additional "niccing") when I switched to vaping last yr.

So even if I smoke 30% more than I used to I'm probably consuming significantly less harmful chemicals in the end, including nicotine. Which means it will probably be easier to quit vaping than cigarettes, especially as I could taper the nicotine percentage from 6mg -> 0mg over a period of time without adjusting behaviour.
