This is seen in heart patients who take their first dose of nitroglycerine (or related drugs), but then tolerate it better later on. Again, I offer this only as a thought that arose when I read your initial message.

I find it quite strange to have worked in darkrooms of all sizes for 55 years and in many locations around the world while never experiencing this headache thing previously. Obviously there's something causing it and makes one wonder if there has been some collective "chemical assimilating" these many years? And with the break of many months to digital - computer printing followed by the exposure to chemistry it begins to show an accumulation has built up. Leaves one to wonder about a couple of buddies who developed lung cancer from the days of "powder preparing darkroom chemicals" and went to the big darkroom in the sky before the advent of digital printing :-( Must look into this somewhere, as at the moment we do have a considerable amount of darkroom time before us over the next couple of months. Thanks for you comment on this matter. ted _______________________________________________ Leica Users Group. See http://leica-users.org/mailman/listinfo/lug for more information
