Thanks for the advice Andrew :) Actually I never crave a particular kind of food; I would crave a taste... and today I wanted something sweet :P guess that's why I ate the doughnuts.
Oh I wanted to ask you guys if chewing gum is OK? (I would think it's not that good, but at school it would be great to make the bad mouth smell dissapear... If it's not OK I think I'll just take my toothbrush and toothpaste with me, to school :) )
