So for an update:
My vaporiser broke shortly before I went to Amsterdam, when I was too nervous to not smoke, so I was back on the fags for a week or two (duty free, man, it'll be the death of any nicotine addict).
However all the time that I was smoking, I missed my vaporiser dearly. I actually prefer it to cigarettes now.
So once I ran out of cigarettes, I went back on the vape and now here I am - 56 days smoke free (sans one joint in that time, which I don't count; it didn't make me want to smoke, at all).
My longest smoke-free period since I started was twelve weeks, which was just cold turkey but I spent that entire time wishing I had them. The vaporiser cuts that out.
By New Year's, I will have been around four months smoke free, possibly more, I've not done the maths, but that would beat my record, and it's at that point that I plan on starting to phase out the vaporiser as well, because even though it saves me a shitload of money (over £200/$400ish in these 56 days alone) it's still an added expense I don't need. Plus because the vaporiser is guilt free, I can still keep it on me, keep it charged so that if I feel a slip coming, I can use the vape rather than a cigarette.
Basically, things are going well. And my first big test will be this Saturday when I'm at a party. I bought a second vape battery entirely so that I had some guarantee of it working all night.
