Could you at least try to get an over-the-counter antiemetic ?
Possible over-the-counter antiemetics (will depend on your country)
Anagraine (metoclopramide eg Australia)
Buccastem (eg UK) / Nausetil (eg Australia) (prochlorperazine, note : has higher EPS risk)
Other over-the-counter antiemetics
These may be less effective, but could be used if in a hurry, etc, though ideally it's better to get metoclopramide (or prochlorperazine)
"Dramamine" or "Gravol", or anything that says "dimenhydrinate". Should be widely available.
Meclizine ( eg Dramamine Less Drowsy, check meclizine is on label )
Metopimazine/Vogalene (eg France)
Diphenhydramine ( eg Benadryl or Nytol, check diphenhydramine is on label )
Peaceful pill handbook states that cannabis is an antiemetic, but if you're not used to taking it then I'm not sure if it's a good idea.
