> I can be fall down drunk 24x7 the whole 10 months my wife is pregnant. Not going to affect the baby.

Ironically, it probably will. Having a husband be that drunk would likely stress the mother, which does indeed affect the baby.

> Also, can I decide what my wife puts in her body?

If you're a husband whose judgement and word she can trust, I'd assume that she would take your opinions quite seriously.
