All antiemetics / antihistamines / didn't help and/or made me unbearably drowsy.

It was at a point that I was setting an alarm for 4.30am to eat something and doze while sitting up for 30 mins, so I could take the pill and sleep off the worst of the drowsiness from 5.00 to 6.30am, then catch the train from 6.30-7am, but by the time the drowsiness was wearing off (around 9ish) I was feeling nauseous and chucky again. So they weren't actually assisting, ITMS. And every day, the "relief" period reduced, so after a week or so, I was actually being roused out of the drowsy period by the nausea and vomiting returning. Awesome.

But even Maxalon makes me drowsy, so maybe I'm just particularly susceptible ...

One thing that helped when I was pg with DS1 (but not DS2) was Pariet - because apparently a lot of the nausea was due to reflux. Worth looking into?

Either way, I really hope you find something that helps. Having had m/s for 32 weeks with DS1 and 37 weeks (yes, conception to c/s morning) with DS2, I wouldn't wish m/s on anyone.
