I've had a lot of success recently forcing myself to do something "boring" in the morning, while I still have willpower remaining, avoiding high-stimulation activities (internet/apps/junk news etc.) until later.

After getting better at beating procrastination, the main problem has been is the feeling that my brain is totally dead and "heavy" after working on mentally-taxing things for hours - napping seems to help with this, but I can't always just nap whenever I want.

Also Chrome plugins to block Reddit and HN (sorry, HN).
