You can use the drug Meclizine (Bonamine) if you can find it but I believe it has been discontinued by the manufacturer (at least here in Canada). Another option would be Betahistine (Serc) however it is prescription here in Canada but I'm not use about the US. If you can't get either of them then Dimenhydrinate (Dramamine/Gravol) will also help some but not as much as the others I've mentioned.
Lastly, time will heal all...
