There's a lot of articles on SOTT about smoking and nicotine. You'll find a good selection listed
here. Here's two on cognitive performance in particular:

EDIT: As for dealing with sugar cravings: One thing to keep in mind is that on the ketogenic diet, carbs are replaced with (animal) fats, which are very satiating and satisfying. This is the key to transitioning: without adequate fat, cravings and/or tiredness will always remain. But some people still need to struggle for an initial period before the cravings go away.
For some reading on the ketogenic diet, you can check the
"Recommended Books: List and Guide" thread. The second post contains the guide section for health and diet, and points to further information.
