Hey KaraC: Crikey! Are you sure all these sleepless hours are good for you? If you read books about prison camps, keeping people awake for days is Standard Operating Torture. After constant sleep deprivation, people start hearing voices and seeing things that aren't there. Have you considered taking less credit hours and having more free time? The reason I ask, is that some of my friends who powered through college to get their majors, all ended up in careers that had NOTHING to do with their majors--all out of choice. They burned themselves out.
Anyway, you need to take some time off so you can be a Potterhead. Right?
