Dress Code, a New York production company, decided to make an animation showing the withdrawal symptoms you can get when you stop drinking coke. It was based on the true story of one of the studio directors who became far too addicted. He realised it needed to stop but discovered side-effects to the withdrawal that he was not expecting.
Hopefully no-one has had this feeling quite to that effect but I'm sure we can all sympathise. When deadlines are approaching coffee and sugar can easily become your best friend, then there's the struggle to get back to your normal routine a few days later!
