hi beth...
if you are really scared you might use, i agree with the others that you should look for another job. perhaps you know someone who would let you clean their house? (i do this part time, and make very decent $$ off the books...) remember, your sobriety comes first.
if you really don't feel that quitting is an option, maybe you should take things (like a book... the Big Book
, knitting, whatever!!) with you that will help you stay busy during down time and out of trouble. and when work is done, always make it urgent that you leave right away. (i'm meeting with friends, whatever. and to say you're meeting with friends is no lie if you're coming here to SR!)
best of luck...
