Cramming for Papers

According to the article of "The Danger of Cramming", cramming can reult in unpredicable outcomes especially with the use of coffee or other stimulants. Probably everybody knows this viewpoint. But sometimes I can't avoid cramming. I studied late last night for my papers. Actually there was plenty of daytime to finish the homework. I just did not want to do anything except watching TV and wandering around the Internet. Late at night, when everything was so quiet, I realized I had to do sth. Maybe it is in nature!
