I am extremely stupid in that the last few years I've taken up a bit of light smoking over the summer months. It's an association with sunshine, beer gardens and ice cold drinks that I struggle to break. Last year I quit cold turkey in September, became instantly ill and stayed ill for 6 months. Started again in April (I KNOW!) and became better. 
Anyway, it's time to quit again and I wanted to avoid the 6 months of feeling crap again so I've just bought an e-cig thingy, thinking it will be less brutal than cold turkey and better than smoking proper fags. (Have been on anything between 1-5 menthol fags a day since April. More on nights out.) Thing is, I'm prone to being anxious about my health and am wondering how safe inhaling these e-cig vapours are. (I AM FULLY AWARE HOW UTTERLY ABSURD ON EVERY LEVEL AND HYPOCRITICAL THAT SOUNDS!) I've bought through Totally Wicked who sound like they regulate their products better than most.
I'm planning to stop completely ultimately but thought that this would be the way to go short term. What do you think? (I'm neurotic and utterly illogical, I know...)
