use lemons! not lemon juice, but actual lemons. take 4-5 of them, cut them up and take them into the tub with you and rub them all over your skin and all through your hair. rinse off, then repeat, then take a bar of soap and lather like there's no tomorrow. rinse off, then repeat the whole thing with the lemons and then rinse with lots of water.
this is a trick coroners use to get the eau de corpse off their skin and hair. if it works for dead stench, it'll probably work for sulfur smell
