Promethazine
"I would rate this an eight.  Unfortunately I found that if I take it when I am already nauseated (the kind where you know you will be throwing up in about an hour) it is too late.  And this medication burns my throat when it comes back up.  (sorry to be a little graphic but this IS a nausea/vomiting medication.  I have to pay really close attention.  If I have any vertigo that day then I take one.  Otherwise.  like I said...  it doesn't help.  Rather like vicoden and a few other pain relievers, that won't stop your toothache once it has taken hold.  I hate taking it when I am not sure.  It certainly DOES make me sleepy.
