I've been keeping up with this program fairly well. I've had the stomach flu for the last three days, so I've had a bit of a blip. That actually effects just about every one of the parts of the program. Last night I slept only 3 or 4 hours for example. And it's hard to swallow fish oil when you can't hold anything down. But until the flu hit I'd been doing fairlly well, and I'm not depressed at all.
I got my light box yesterday, and I'm using if for the first time right now. I'm actually finding it a bit unpleasant at the moment, but that may have as much to do with flu as with shining a bright light in my eyes first thing in the morning.
