For instance caffeine withdrawal causes severe headache and nausea. You actually get sick. I believe that is what happens with heroin and cocaine. Something like sugar, on the other hand, screws up your insulin levels while you're eating it, but I don't believe refraining from sugar actually causes physical illness. At least I never had that problem with sugar and other foods I've given up (bread, mostly). I can believe in food addiction but I believe it is more psychological than physical.
