ScienceDaily for August 18, 2010 reported on attempts to stop smoking.
Dr Erskine and his team set out to test whether smokers experienced behavioural rebound -- the phenomenon where trying not to think about something leads to an increase in the behaviour. Their previous research into eating behaviour and thought suppression showed that people trying not to think about chocolate subsequently ate much more than people who were deliberately thinking about it. However, previous studies only examined behavioural rebound over a period of five minutes, rather than days and weeks.
