Early pregnancy nausea medication

I’m an icu registered nurse and tried to really hold off taking nausea meds but at work I really just can’t keep it together. My ob prescribed zofran and Doxylamine-pyridoxine. She asked me to not take the zofran regularly just when I was feeling really sick. My question is have any of you taken Doxylamine-pyridoxine? What have the side effects been like for you? I tried to hold off as long as I could but at this point I can’t even hold down more than a few sips of water
