  Hi giggles
  
  I answered a question a little bit like this here: http://ias.im/100.1209
  
  But other than this a sugar rush can also make us hyper, this is when there is more sugar in the blood stream than is needed by the body for energy. This extra sugar needs to be expended before we can return to normal and it is used up at the same rate as if we had less sugar in our blood. The extra sugar might increase our heart rate, make us more excitable as the brain uses up lots of the sugar, and we feel hyperactive!
