And once weaned off of whatever the addict is addicted to, then what?

Is it OK for a crack addict to have a reasonable portion of crack? Or an alcoholic to have a reasonable portion pf alcohol? Or an ex-smoker to have a reasonable number of cigarettes?

No it's not OK. No one would ever suggest that. And if you think that a food addict is only addicted to sodas and Ruffles, you're mistaken and have never seen me at a sushi bar.
