nausea/vomiting
"I absolutely live by Promethazine.  I keep it on hand when I'm nauseated. It's such a versatile medication. It sedates you but not in the way that benzodiazapines or narcotics do.  



Lastly, whenever I go out drinking, I take this at the end of the night along side a bottle or 2 of water..I wake up the next day not hungover or nauseated!  It's a fabulous hangover "cure"!!  ;)"
