Part of the reason that ecigs are so effective is that you are still going through the motions of smoking. A good chunk of the addiction is the actual act of bringing an item up to your mouth, inhaling off of it, and feeling that go down your throat and into your lungs, then seeing it when you exhale.

There are alternatives like nicotine patches, nicotine gum, etc, but if you didn't like ecigs, then those have a very slim chance of working for you :/
