The only memory I have this movie (or possibly tv episode) is a scene of a group of people enjoying themselves in a living room (or maybe a different room) near a christmas tree.  They are happy and enjoying drinks of some sort and suddenly at least one character takes a drink and starts puking and vomiting like she had been poisoned.  I remember it being a very dramatic scene and appeared to have that mid-90s feel to it.  In color and the language spoken was English.  Thought I imagined it but found a similar description on another site today.  Can anyone help?  I’ve been looking for years.
