Oh, I'm willing to bet that's your main problem. You could do/try a number of things:

• Spend some time in front of a very bright light first thing in the morning for 30mins-1hr. Classic light therapy. The sooner, the better, but if you can only do 10 mins at a time or something, some is better than none.

I actually just replied to someone below with this, but you can make your own light therapy lamp with the GE BR30s:

Here's what it looks like, and here's what you'll need:

• - GE Sun Filled Daylight Bulbs (5)
• Table Lamp
• 5 in 1 E26 Splitter

It'll put out around 10,000 lux at 1 ft, making it “light therapy” capable, and it'll run ya about $70 give or take.

Other than shining some bright light in your eyeballs sporadically throughout the day, you could buy a Luminette 3 (affiliate link, btw). If it's something you could wear and still complete your work, it'd likely be more than worth the cost to improve your sleep quality, in my opinion.

And ya know, try to get outside for lunch or something, eh? haha

As far as having the dim light be better light, yeah I would, if you can swap out those bulbs for some higher quality light, why not? If you have to any physically color-sensitive work, the higher CRI and TM-30 won't hurt either.

Good luck!
