On coughing too much to smoke

I don’t smoke (and never have) but DB does. Or at least used to.

He hasn’t smoked AT ALL since Friday.

DB is so ill atm that he can hardly breathe, never mind talk; smoking is unthinkable.

Much as I want him to get well as soon as possible, it would be soooo good if he stayed ill long enough to get through the cold-turkey of giving up the cigarettes, before getting better, on the grounds that he’s not feeling good anyway, and probably/maybe couldn’t be much worse…..

What are the chances?
