Give me a drink!

Pt admitted s/p kick to the head while intoxicated which turned result in a carotid artery dissection. He was admitted for BP monitoring (and other things) and told not to drink caffeine. Before discharge he drinks a mt dew and starts having a panic attack (w/out xanax b/c docs took it away), BP was fine and he wanted to leave so we d/c’d. Gma calls back an hour later, after driving 45 minutes home, cause he’s vomiting all over and having a panic attack. Back to the ER
