Prochlorperazine
nausea/vomiting
"It's not often I get norovirus, but when my stomach is empty and the heaving persists, this helps me. It does make me tired. So I sleep it off. By the time I wake up the heaving has ceased.  Maybe I've experienced some dizziness. But with a virus, I wasn't intending to clean my house or run a marathon! I'll just take heaving cessation!"
