Sleeping in a box

When the 40 hour famine came around I slept in a box. At first I wasn't nervous but by the end of it I was tired and I never want to do it again.  The box was small and uncomfortable. At the start I was using a blanket as a pillow but it started to give me a headache so I found a pillow and used it. The second night was better than the first one and I actually got some sleep. It was the worst experience that I have ever had and I never want to do it again.
