When i first stopped I used the eciggs but i had no idea how much of the stuff i was using because each filter is approx two packs but there is no point in which you are told how many 'ciggs' worth you have smoked. I also used the patches. The combination of patches and eciggs did help but i'm pretty sure i overdid it on nicotine at first.
Speak to your doctor and/or pro (and hopefully free) stop smoking service.
I don't trust the eciggs at all they are just another way to keep people addicted to parting with their money and I also imagine there will be associated helth risks as they have only been tested in short term controlled studies. That being said as a temporary measure I think it's whatever gets you throught the night but be prepared that you will have to go through withdrawls all over again when you stop the eciggs.
The things that worked best for me personally was lollipops. You can get corn syrup ones from the health food shop, I literally went through bags of them but they were the best at dulling cravings.
Good luck with it
