I found it easiest to go pretty much cold turkey. I gave up fags in November 2012 after 25 years of moderate to heavy smoking and went straight to electronic. I initially had the occasional tin of cigars as a social function treat but evetually knocked those on the head as well. I'm now totally smoke free and feel so much better for it. I don't even use my green smokes anymore, it's just me and my V3! I would never go back to smoking again and wish vaping had been an option when I started on the ciggies in the 80's!
