Hi Bev - I think more people think of SAD as standing for Seasonal Affective Disorder - so it might be quite confusing.

This is where some people who live in harsh climates become depressed due to the lack of sunlight in the snowy/rainy seasons and many have to use special lighting several times a day to relieve the symptoms.

There is a section on this board that includes Fibro/Chronic Fatique and SAD - link below
