with my first pregnancy I used a compounded prescription from my doctor here in Oklahoma...It was vitamin B6 and Doxylamine. Compounded means they basically crushed it up and mixed it then put it inside a capsule...Something like that...LOL. Anywho, for my 2nd pregnancy I got morning sickness before I could get to the doctor so I just went to walmart and bought some vitamin b6 and unisom (with doxylamine as the active drug). When I got to my doctors appointment they said it was okay to keep taking that as needed but that if I wanted they would give me zofran. I took the zofran and it barely worked compared to the first option.
I LOVED using B6 & Dox for my morning sickness. It was the only thing that worked for me. Well, the zofran worked if I had a light case of MS but mostly I used the other stuff. Definitely talk to your doctor about it before you use it, but i swear by it. LOL.
