Its far from easy, vaping helps in the beginning, better than going cold turkey, I couldn't of done that, but vaping isn't the cure for the cravings, however stick with it, the first week was the hardest, once I got through that it became fun trying all the different flavours etc.
If the cravings are too much for you, up your nicotine content, I started on 18mg nicotine to cure the cravings and was vaping constantly, and I mean constantly, morning till I went to bed at night, had to be 5ml (half a bottle a day), I'm now on 12mg when tooting and 6mg with lung hits.
Its easy to drop your nicotine content when you're just pure vaping, so don't be afraid of starting high, when all you can taste is the nicotine tobacco kind of taste, its time to drop a little, don't forget you can also mix flavours yourself, my Mrs vapes 12mg nic menthol with 0mg nic Apple 50/50, gives her about 6mg nic, for me I grab anything 16mg and 8mg that I fancy mixing together, banana and vanilla custard are one of my favourites, mix them together to give me 12mg nic.
Do away with the cigs all together, if I had those in my pocket, I would have chosen those over vaping a few weeks ago, out of sight, out of mind, it helps, as someone else on here mentioned though, it was 2 or 3 weeks into vaping that I got a chance to stand by anyone who smokes still, it was a guy I was delivering to, omg it smelled terrible, I couldn't believe I used to do that, explained to him that I couldn't be near him whilst he was smoking, he completely understood, one of my nicer customers.
