Upper Hand: Zombie Apocalypse

You take a more surveying look at your surroundings and realise that you do have some time to drink from this man (slow, obese zombies coming from the end of the aisle and behind you is blocked off by a neat stack of boxes and a pile of felled cans).

You yank him roughly towards you and he yelps in surprise. His face directly in front of yours and you look directly into his eyes using minor vampire hypnotism which makes him easier to drink from (you kind of wonder how hes feeling right now, the way hes looking at you makes you think that 'If I Fell' by The Beatles is playing on loop in his head).

You lower your mouth to his neck and bite into his veins and suck out the blood deeply; you drink your fill and feel rejuvenated within seconds, the guy however passed out in your arms from blood loss (he definitely won't remember that later, due to the hypnotism pre blood drinking). What to do with his unconscious self though?
