I'll definitely look into a SAD lamp. I've also started efforts to visit a doctor. Considering how long it's been since my last checkup, I wouldn't be surprised if there were health issues making things worse. Other than that, I'm focusing mainly on diet. It's a little tough, as a single person it can be difficult to keep the right amount of food around; too much and it'll go bad before I finish it, too little and, well, you know.
