My ex did it, he joined AA and had been sober for about 2 months when he applied for the landlords job at a pub in London he had been working in. He got the job and as far as I know is still there, nearly 4 years later and sober.
Being in London he had huge numbers of AA meetings he could go to and his mentors gave him an awful lot of support. I always questioned him about his willpower, he said this was the only way he could do it facing up to his problem everyday head on, if he could do it on a daily basis he wouldn't be tempeted when he went out with friends. He was incredibly dedicated the the AA's teachings (constantly reading their literature and phoning freiends) and I think this is what got him through it, coupled with his incredible willpower.
