One thing I have found to be of value in the fight of winter depression...it may sound a little weird or too simple but I was reading the back of a carton of epsom salts on day and it said "for relief of winter blues" pour two cups into a hot bath. It sounds like no big deal but it really, really works. There are times when I start to drag and can't seem to get motivated. I get really tired and something in my body just feels off balance. I take a bath with epsom salts and it seems to balance something. It's the difference between night and day. It doesn't get you wired but it brings the energy level up and puts me back on an even keel. Trust me...give it a try. Another thing I have found that helps is watching what I eat. There is a book out there called Potatoes Not Prozac. It's a great book! I don't follow the diet exactly but it helps to understand the relationship between brain chemicals and blood sugar levels. The author pushes you to cut out all sugar (which I don't) and boost your intake of protein and complex carbs at certain times of the day. I find that the more meat I eat, the better I feel. Just some thoughts, hope it helps!
