I think the thing to remember about nicotine addiction, is the psychological addiction is harder to overcome than the physical addiction.

That's why it can be very hard to switch to NRT or e-cigs even though you are getting enough nicotine.

It's the whole process of buying cigarettes, lighting up & smoking them that is ingrained into you. Obviously e-cigs help by keeping the smoking element, but at the same time... psychologically you think you aren't getting your fix. We think the cigarettes themselves are something we like, but that's just brainwashing... it's the nicotine.

I found it helps to realise that you are just a nicotine addict plain & simple. Cigarettes are just a delivery method. If you can drill that into yourself & realise you aren't missing out on anything not having cigarettes then you'll probably adjust to e-cigs without too much hassle.

It's not something you can force though. The twice I've quit, I've always had "eureka moments", which suddenly made it so much easier. It's just a mind set.
