So when I say 'you stinker' it's for real?

I heard that chocolate can be a laxative, so I guess it affects your digestive system. Can you give it a miss for a short while? Remember it has caffeine in it anyway. Replace it with something else yummy though, Frosty Fruits or sour worms...mmm....

Lollybaby might be onto something with the excess vitamins though?
