yes, way to go on day one, rednails!
i, too, was sober during my two pregnancies. it was easy, and looking back i think that's because i knew i could and would drink again after the births. it wasn't quitting, then, as such, but just postponing.
and possibly the hormonal changes influence things in ways we don't quite understand yet. i was listening to an allergist on our national broadcaster today who said it's not uncommon for pregnant women's allergies to simply disappear and then re-appear once the baby is born.
