She has tried Unisom and only receives marginal relief. She also is trying mint and papiya tablets as well as vitamin b drops. She cannot take prenatal vitamins so she tries to take child vitamins toward the end of the pregnancy. She has been taken to the hospital in the past for dehydration from the vomiting. She has very healthy babies but suffers greatly in order to have them. Isn't there something she can take that won't affect the baby? THANK YOU>
