Take a dose of Tylenol
PM with cold
compresses over the eyes, a light dinner with plenty of water and a good sleep is all you need now.
A dose of Metoclopramide
tablet will relieve your nausea
. Avoid coffee, tobacco etc as it worsens the symptoms instead a cup of ginger tea will help.
If your symptoms persists tomorrow morning seek your physician for further medications needed if any.
Hope you get better soon.
