Re: Does it hurt to be shot by phaser?
But even if you don't feel pain when stunned you feel like crap when you wake up it seems.
Cochrane complained about it when he woke up in First Contact. Though admitted it may be a hangover... though given he lifted off at 11 am and was drinking for the better part of the morning, it's safe to say he was drunk up there and not hung over.
