I had terrible morning sickness my first trimester. Here are some tips. Avoid anything with cooked milk like Alfredo. Avoid anything red. Red digests differently. Drink water dehydration is super scary if you can't hold anything down. Also anything super cold helps a lot so get a slushy or some ice cream or popsicles. Laying on your right side is also helpful. And everyone always told me crackers before getting out of bed it didn't help me but it might you
