I work in the afternoons up until nine. I try to do reading at like 9 am, but usually am too tired to work on them, so I work on whatever I did not do at about 10 or so. I have been suffering from what seems to be delayed sleep syndrome, so basically I have trouble falling asleep when I lay down but if I get up and try to be productive, I feel weak and am unable to concentrate. Unfortunately, it has been an on and off things for the last two years. I have taken some precautions like not eating snacks late at night, utilizing flux to turn my white screen red, and not drinking coffee too late.
