SAD?...Maybe you just need to go sailing.
If the prospect of a long, cold winter is not filling you with a warm glow right now- perhaps booking some fun in the sun sailing on a 60' race boat at the famous St.Maarten Heineken Regatta will give you something to look forward to over the next few months whilst you are shoveling snow, scraping ice off the car and driving to work in the dark.
Now that's what I call a remedy for Seasonal Affective Disorder.
