For me, tapering nicotine was about as hard as getting daily exercise. Instead of a bit of muscle soreness or tension, I'd get a mild headache towards the end of the day for the first few days of a two-week cycle. About halfway through the two weeks it would usually stop, and while I'd still want the extra cigarette, I wouldn't get a headache from skipping it.

I suspect if you're using enough nicotine that you can't feel the effect of a cigarette, you're probably using a lot more than I was getting from smoking. I'm not sure if my advice is equally useful for you, but I hope you manage to kick the addiction cycle at some point.
