Well, you did better than I did on AC.
I was super unlucky and not only did I react really badly to the AC, but the meto did nothing for me. Four hours post infusion I was hurling every 5 minutes. Even the extra intramuscular shot did nothing. Turns out there was a significant medication clash we didn't know about.
I ended up being hospitalised for three days.
ANYway, my sob story isn't the point.
The point is that there are other options for treating nausea. If meto doesn't work, ask about extra steroids, or ondansitron, or cyclizine, or whatever. They all have side effects, and they may or may not be right for you, but there ARE options.
