She's oinly successfully given up twice, one per child, but ultimately went back on to them a year or so later. Willpower is a non starter with her, patches and gum also failed. Of course I'm not really thinking about taking it up I was just after the negatives of this approach as I bought her the e-cigs. I'd be very interested as to why GP friend thinks they're carcinogenic as as far as im aware nicotine isn't and nor are theatrical smoke machines, but if it's the case then it seems to go against the whole reason for giving up. Perosnally I find them innoffensive the vape smell doesn't linger, I think they're being banned necause people react emotionally to seeing it nowadays and they're avoiding rows. I did try it though just to see, it tasted pretty grotty and I actually fouind the nicotene rush really unpleasant, it had been a a while after all!!
