Stopping B6 & Unisom

Hi ladies. Anyone out there who had been taking B6 and Unisom for nausea that has since stopped taking it? What was that like for you? I had been taking from week 7 to 14. Have slowly been decreasing my dose. Now 2 days off all and I’ve been crazy sick. The nausea and vomiting is terrible. Did it take a few days to adjust and then you felt better again? Or when you stopped you felt fine? Or did you start the meds back up again. I was looking forward to being done with it. TIA
