What mg combo did you take? How many times a day? And did it help?

I had very bad morning sickness week 6-14 and then it stopped. I never threw up every day, never was nauseous, and didn’t want to take medicine for it. I’m now 22 weeks and I’ve been throwing up again every day for the last month. It’s a combo of mucus/coughing/nausea now because I was very sick for a while. My doctor said to try the unisom B6 combo and said take half a pill of each up to 3x a day. But they come in all different milligrams! I just bought 25mg unisom and 100mg B6 and don’t want to wait till morning. Help!
