I had several questions about the recommendations that Lilly had 
for insulin storage and use, so I called and was able to talk with a 
very forthcoming representative.  As to the question about sunlight, 
other than its effect in raising the temperature of the insulin, the 
deleterious effect that it has is on the cresol perservative.  Sunlight 
tends to turn the cresol brown, and as the rep. pointed out, nobody 
wants to inject a brown insulin.  That is why we are warned about 
keeping insulin out of the sunlight, again, other than the warming.
