Lights and making sure I'm hydrated helps. I seem to have no problem drinking enough water in the warm months but in winter...ugh.
Music is another helper. Something 'peppy' that I know the words to and can sing along.
In winter, I tend to eat foods with a higher fat content which can make me sluggish too. Try some citrus or watermelon. Fool your body just a bit.
I also take vitamin D supplements from October thru April. I had my doctor take a base line first. While it's highly unusual to have too much vitamin D, it is a fat soluble vitamin meaning that your body stores it rather than eliminate what it doesn't use on a daily basis.
