<That's what I'm thinking - going "cold turkey" no matter what the item is usually causes somekind of withdrawl symptoms - even if just "psychological" instead of "physical" (like video game addiction versus addictions where something is ingested). >

Both video games and sugar target dopamine in the brain's reward center in susceptible individuals. The withdrawal symptoms of both are caused by dopamine deficiency even though they seem so different.

The key is the brain's reward center. Most people probably won't experience withdrawal pangs if they (say) stop eating spinach or listening to muzak because these aren't terribly exciting and don't trigger dopamine in the reward center in most people's brain.
