pawm, I have the same problem as you. I actually forced myself to get up at 8 this morning, which is probably why I haven't gotten anything done! Someone mentioned this in a thread some time back--have you noticed a time when you feel you are most productive? I find around 7pm, I start to feel more awake/alive. I'm useless in the mornings. It's impossible for me to sit and read for 6-7 hours solid, and when I do I feel absolutely dreadful (achy, irritable, exhausted, sick) for the rest of the day. I'd love to see a list of the most common health problems experienced by PhDers!
