I am sorry to contradict tilt, but these formulations are both correct in AE, and they do indeed mean what Moon Palace thinks. The second might be more common than the first, and both are a bit informal and perhaps also a bit dated.Could you also say simply 'writing does me good'? Or 'it does me good to write'?
I beg to differ: "writing does me good" is fine (as far as I'm concerned). It could be collloquial, though, but it's certainly used.Désolé mais ça ne veut rien dire du tout, pour autant que je sache.
Personnellement, je dirais plutôt Writing makes me feel good.
