Small, frequent meals and taking things slowly - By eating smaller meals more frequently throughout the day, you can help alleviate your nausea. It is best to avoid having your stomach completely empty or completely full, since both can make morning sickness worse. If nausea is worse when you first wake up, try having a box of soda crackers on your night-stand and nibbling on them or sipping weak tea- before getting out of bed. Rising slowly in the morning, instead of jumping out of bed and rushing out the door, will minimize morning sickness (and also light-headedness).
All The Best & Congratulation!
