Ben Affleck is struggling to stay off cigarettes.

The 'Argo' director is trying to busy himself with domestic chores in a bid to conquer his nicotine addiction after his wife Jennifer Garner - with whom he has daughters Violet, eight, Seraphina, five, and two-year-old son Samuel - told him to quit.

A source told National Enquirer magazine: ''Ben's promised to ditch the butts again, but now he's just a bundle of nervous energy and is doing anything to keep his mind off cigarettes.

''He comes up with all sorts of household projects and cockamamie schemes to stay busy, and it's just one misadventure after another.

''Ben decided he needed to keep his hands busy, so he built a bookshelf for the girls' playroom. It would up comically lopsided, with the books tumbling off of it.''

Ben has also been spending time with his children and he has even been teaching the toddler Samuel about his male private parts.

Jennifer previously explained: ''He loves his girls, but he's serious about his son right now. So, he taught him about his bits. ''He taught him about his P and his two Ns.

''Now anytime we pass a dog who's walking on the street or we're at a zoo or something, our poor little son is crouching down and looking up.''
