The only reason why I went an entire day without a cell phone was because of a dead battery. It actually helped out in the long run because I had to go a day without my cell phone for a Design class as an outside assignment. Another thing that helped greatly to distract me was that very same day we held a marching band contest at the school, so I was busy running around all over the campus guiding bands, running judges sheets, moving equipment, etc. It was a crazy day, but it made the lack of usage on my cell phone easier than it would have been if I wasn't always busy.
