Why am i so hungry all of a sudden i.e just today?

well I eat like a horse anyway so don't use me as an example, but yea the aftermath effects of drink vary from person to person so if you aren't usualyy like that, it's more than likely from lastnight! I remember one night (I'm just finished my freshman year of college) I ate 5 packets of salt and vinegar crisps in less then 5 minutes and they were cheap ones from the local store and tasted as if they were just grease and vinegar, I only ate them as the drink made me soo hungry!! So you will be fine, it's just today!
