I've kept overall carbs fairly low since 2010 thanks to your work. But I find this significantly impacts my ability to perform intense mental work (writing and analysis) unless I add some sugar, and I read recently that you use nicotine when writing. I've tried adding salt, potassium, etc., but only sugar seems to help. Any advice or thoughts on why and what to do?

I'm definitely not in full-blown ketosis on a consistent basis, so I'd likely be in that no-man's land. A typical day would be 60-70 grams of carbs, with a good day being ~45 and a very bad day being ~100.
