Caffeine is bad and morning sickness is good. Well the caffeine is bad is a Duh! Caffeine is a drug and you need to be very careful about drug and alcohol intake (among other things) during the first trimester of pregnancy when the fetus is forming.

Morning sickness is good was a surprise! "the same hormonal changes that cause nausea and vomiting contribute to a healthy pregnancy." If you say so ... but it sure doesn't feel healthy when you are having it!
