If you wholeheartedly want to quit. You will be able to. If part of you still wants to smoke, it will be a struggle.
It's your responsibility and your choice. Addiction or not. Whether you buy tobacco. Light up and smoke a cigarette is entirely your choice and its as simple as making the choice not to do it despite the urge to. I'm not saying its easy, but it really is that simple. It will work if you want it to work, if you make excuses, you don't want to quit that much. You might have occasional slip ups. But remember a slip up doesn't mean you have to fall off the wagon and give up giving up.
E cigs won't taste the same, that's not the point the point is to give you the substance you're addicted to in as close a way as possible without the damage. If you're going to use them to help you, invest in a good one like totally wicked and some good liquids and don't expect it to feel or taste the same, expect it to take the edge off your craving. It makes you cough... Really... Didn't smoking when you started.
If you wholeheartedly want to stop, stop making excuses and do it. If you don't. Carry on.
