B6 & Unison for morning sickness!?? I went to the ER a few days ago for excessive vomiting and nausea and they prescribed me some "diclegis" when I got to the pharmacy to fill it the pharmacist told me it was a combination of b6 and unison and if I wanted to save money jut buy that instead of paying for the prescription!! Anybody else heard of this or tried it?? TIA
