For those of you who are truly interested in this problem, best I can tell it is an imbalance in one's bloodsugar that causes the sickness. I am fairly certain that some poeple are immune to it or have developed such a tolerance that they can not be affected by the nominarl nicotine found in a cigar (or 10). My father had not smoked cigarettes for 15 years before he started smoking cigars but still, never became afflicted with this syndrom. SFLarry above has never been affected. Why? Does one's nicotine tolerance last a lifetime? That doesn't sound like any tolerance I'm familiar with.
Boiled down, this is one reason I started developing a taste for mild-medium strength or vintage cigars. When I smoke on an empty stomach or a cigar that lasts longer than the meal I've eaten takes to digest, this happens to me; every time. Indyrob's first post is the appropriate solution. Spoonful of sugar makes the sickness go away.
