I gave up tobacco 13 months ago. After a couple of false starts (Blu, 306), I got a 510 and quit; but only with the help of 36mg. e-juice. Over this year, I have gradually cut down the NIC level from 36 to 24,18,16 & 10-12mg. with absolutely no cravings or side-effects. Today, I got my first shipment of 6mg. juice from Halo (and waiting for my order of 6mg. juice from ivape.net). I'm still getting excellent vapor and TH with the 6mg. juice and looking forward to 0mg. in the next few months.
It's been a long process, but I have never felt better and have had countless other benefits; I don't stink, my clothes don't stink, my house doesn't stink, my teeth are whiter. and (most importantly) I'm not adversely effecting my family and friends as I once did. It's a Win, Win situation!
As for the oral fixation, I kinda like that and think I will continue vaping for quite some time.
