Advice & Tips: I have had Seasonally Affected Depression since I was a kid when my grades always dropped in the January-March grading period.  Now living in the NW where winter nights are long and days are often dark, my full-spectrum light has really helped especially when adding 400 units of daily liquid Vitamin D each day in the winter.  Caution:  the cheap lights don't work as well. 
Cost: $100-199 monthly
