I quit for ~5 months with our first (we had spontaneous fraternal twins) and ~4 months with our second. It would've been longer but we conceived the first month we started trying in both pregnancies. It seemed self-evident to me, at the time, that I should do everything I could to "clean" myself up. I stopped eating fried food, stopped drinking calories besides milk, ate more fruits and vegetables, etc. My wife doesn't drink so she didn't have to change her lifestyle much.
