TBH - Not keen on the flavoured ones - If you are a smoker, you have an addictive trait, so having something else to get addicted to is not a great idea - in that I mean sweet flavours! Use a normal E-CIG and DO NOT try to give up. It ends up being a side effect, which is far more permanent than you trying to stop. Smoke normally for a week. After this, smoke as you wish - if you only have a few puffs, then go back to what you were doing, then so be it. Don't worry. Slowly you will find you are puffing less and less naturally - then, when you are only on 10 puffs a day or similar, you can play a game in reducing it. There is a really strange effect. You will be able to stand next to someone smoking, and you brain does not connect it with smoking at all. You have no cravings as you are used to 'steam' as it were with no flavour or smell. You get used to nothing, you crave nothing I guess. Been well over a year - never crave, sit next to smokers, never crave or register they are smoking other than the stench, which I cannot believe I smelt like! ALL of the people I know that have continued smoking with e-cigs all went for flavoured ones, or gave up when the coughing start in the first few weeks - this is hair standing back up on your throat (is why your taste/smell improves) previously slicked down with tar from cigs, but does tickle until you get used to it again as the e-cig has no tar. Good luck! Don't try and give up at first - do it because it costs less.
