I suppose I'm lucky. My wife and daughter both have Seasonal Affective Disorder, and it messes with them bad. It never used to affect me, but as I age, I feel the effects of seasonal changes more. My best hope is to hold on through the winter until energy returns and my metabolism starts to ramp up with the return of the sun.
The worst time for weight gain for me is February. The wheels just come off the wagon then. So the more I can hold the line now, the less weight I'll have to lose when losing weight becomes possible again.
