Not precisely, but I've always used it a bit differently -- I put it in everything I vape. But the day I added it, in the morning, that night I realized that I hadn't had a craving ALL DAY LONG... The absence of something is harder to recognize, than the presence of it.
But, given that WTA might be "low hanging fruit" to the gov't busybodies, the way you're doing it is a lot more sensible -- you won't have to go thru the long weaning-down process that I've been doing for over a year now. Your way is also probably a lot less costly! At the time I did it, I was still experimenting with a lot of different flavors, and I feared if I put it in just one tank, I'd just end up sucking on that tank all the time... so I did an end-run around that, by using a low level that I *did* suck on all the time.

Thanks ... I did consider doing it your way, but I'm a bit like @englishmick in that it feels like going back a bit. On the other hand, if the occasional puff stops me from lighting up a cigarette, I'll take it.
