One doctor I've been to seems convinced I've an SAD problem and I'm 
inclined to ageree with him.  However, what exacerbated the problem was 
not a latitudinal change but longitudinal.

I'm at about the same latitude here in California that I was during the 
first 20+ years of my life on the East Coast.  The difference is that it 
rains here through most of the winter and is very gray - very little 
sunlight comes through the cloud cover.  Back East I got much reflected 
light from the snow and I believe the sunlight levels were *much* higher 
as the cold seems to precipitate humidity into frost and the like - the 
skies are much clearer.

You might want to keep this in mind - that sunlight levels can be 
climate-related as well as latitudinal-related.
