text: The main thing is to not lie to your husband.
  
  Is the party a must-attend? In that case you may need to leave him home, or lay out rules like one drink per hour. [I wonder how much the multiple-drink situation may be precipitated by party anxiety.] If you show up solo, you can simply say truthfully that he is not the party type.
  
  Is the party optional? In that case, you do have the added option of not going at all. Since this is a busy season, you can also cite that as a reason not to go.
