Sleep is the cure for me, I have to get home, get the room dark and cold, take promethezine if I am nauseated. The plus is promethezine is one of the few things that really sedates me, I even woke up on Ambien. I had a really bad one about a month ago, only my third so I am not yet to taking preventative medicine. My college roommate had the vomit inducing kind and it was get the room dark, quiet and cold that worked for her too. The worst thing for me is feeling hungover and exhausted the next day. It is like you are punished again.
