Sometimes something really funny will make me laugh for 3-7 seconds.. very short... but I will get light headed almost immediately from the start of the laugh, get numb head, face, leg, and hands and I can barely stand/sit straight... but it happens almost instantly... But on longer laughs nothing happens... I don't get it... is it some kind of rush/chemical release in the brain? something wrong with me?? I mean I've had long laughs where I need to gasp for air a few times and nothing happens.. but if somethings really funny almost instantly I will feel those symptoms... even though its just a 3-4 second laugh.... oh god I just realized i posted this in pc gaming.. I'm sorry mods, would it be possible to move this to general?
