Sleep Issues and Sleeping

So, here's the latest issue with knitting while dealing with fibro. I can't stay awake. I have had to depend on coffee and soda with caffeine in order to do so and now that I'm trying to cut it out, I fall asleep at my desk while I knit. This is taking a huge toll on how fast I knit. So far, the only thing I've found to improve my energy level is to take naps. My production speed is way compromised by my fibro while I try to make items to sell. The last pair of socks, which should have taken about 2 to 3 days took over a week instead. 

They turned out nice, but, Wow, did they take a long time. I hope that eventually I can get past the headaches and sleepiness with time.
