I find watching anything on TV, or going for a drive and singing to a song is good. Especially the singing because you distract yourself by remembering the words and trying to be all proffessional. Admit it, we all pretend we are epic great singers in the car :P Also, if I know its an anxiety attack, I go for a walk outside or a jog because its not a nausea that you will be sick from so exercising wont provoke it.
