Hi Bas and welcome to the planet. Congrats on giving up the smoking it is an achievment for a lot of people. I used to smoke a lot as well, working outside I was not restricted. I would find though that a lot of the time I had a cigarette on the go just for the sake of it and ended up throwing a lot of it away. It would also help with concentrating whilst doing something, some people would have a matchstick in their mouth, you see people sucking the end of a pen. Obviously smoking a cigarette gave you nicotine which would keep you calm in the most stressfull and demanding of situations. I think vaping has the edge over any other method at the moment because there are so many things to look at on the net, flavours to try, kit to buy and different methods of making coils etc, you do not think of having an analogue. Stick a patch on your arm and it`s like what next. Enjoy your stay.
