My wife stopped part way through January (she has had the odd one but now hates the taste). E-Cigs are the way to go. She's now onto Blueberry and Granny Smith flavours as why smoke something that still tastes like a cigarette. Very proud of her after smoking for so long.
If anyone's interested there is a shop in Church Street, Trowbridge that also lets you try the different flavours to see what you prefer.
