I was lucky and don't feel I had to give up anything however have put my thoughts here on each of the points

health? - no - in general, would not give up my health. if my health was suffering to the extent it was affecting my ability to parent or my happiness I would have given up b/f.
career? - yes, for women the ability to have babies has a limited timeframe. I believe you can get a career back after the children are older.
sport? - definitely - but it is not a priority for me.
habit? - Not sure - I don't smoke and don't drink much (chocolate is my only vice!) and DD was pretty much happy with whatever I ate and drank so didn't have to
