I m 6 months running, Still I am not able to eat properly... ..once in a day vomiting ...what to do

A. Vitamin B6 is a safe, over-the-counter treatment that may be tried first for nausea and vomiting of pregnancy. Doxylamine, a medication found in over-the-counter sleep aids, can be added if vitamin B6 alone does not relieve symptoms. A prescription drug that combines vitamin B6 and doxylamine is available.
