Sympathy Hangover 

Someone who is around hungover people and feels the effects of a hangover (i.e. Stomach ache, headache, tiredness, etc.) without drinking the night before.

Damn, everyone was so blacked out last night, but I didn't have a drop of alcohol and my head is killing me today, this is totally a sympathy hangover.
