the only advice i can give u is dont have an empty stomach
although this defies all human logic as u feel so sick how could u eat, having an empty stomach makes it worse. try dry crackers, or plain biscuits, soda water, peppermint or ginger tea have also been said to help some people as well as ginger ale. as hard as it is if you throw it up then u throw it up but something will go in. make sure u drink because the only thing worse than morning sickness is dehydration on top of it. everyone is different and i cant tell u when the hellish period will end but it will get easier, and for most people disappear by end of tri 1. if you throw up excessively the doctor may recommend a medication for you but for just plain old nausea were usually on our own.
