I don't know if three days counts but I don't feel a bit different.
I have a feeling you're supposed to be nicotine free for at least six weeks or something.
Or maybe that was six months?
I think the idea is that once your brain "rewires" itself to be without nicotine, that is when you see the changes.
But I suspect the changes are that you stop having that gnawing feeling of wanting a cigarette?
If so, most of us are already feeling that whether we are using nicotine or not.
Or maybe it has more to do with the freedom from having a habit to support and spend money on?
If so, I guess I can see some merit to that, but I like my habit and I can afford it quite easily now that I've quit smoking.
I guess someday I'll probably have to ask Katiem or one of the others over there.
