I gave up (cold turkey as in hospital!) nearly 2 years ago. I couldn't get on with e-cigs at all - they gave me a sore throat so gave up with them as well.
I put on about half stone when I first gave up but it came off fairly quickly once I stuck to plan, LOL! I was eating raw carrots when I gave up as I needed the "hand to mouth" thing as well.
I've now been in target for over a year.
