Generally I think that is what most people care about. I'm happy it has helped you and your wife so much. It has certainly helped me as well.
I hope no one thinks I'm taking an anti e-cig stance, because I'm not. I'm just questioning the oft-quoted "fantastic" success rate. Debate is good, though I feel I'm doing terribly.
Oh no, I'm sure you're not anti e-cigs!
And it is right that that statistics, findings, conclusions and so forth be questioned. Doubtful statistics, if proven incorrect, cast a pall of uncertainty over everything we say. We do have to be able to back up whatever we say. No argument there.
You're debating well, don't question yourself about that. Your posts are always read with the greatest interest. (By me, at least!)
Cheers
