A Question to the DON ?

I have been in recovery from alcohol addiction and have given my complete attention to my recovery for most of the past year. And because of this I feel I have a new lease on my life. A second chance. I continue my meetings, my weekly counseling appointments, maintaining my health and piecing my life back together . I'll never look at another alcoholic or addict the same way again. For me, this has been the most difficult thing I've ever had to do in my life,so far. So, I'm back in the job market and struggle with how to respond to the typical interview questions,such as, "Why did you leave your last job? Can we call them? " Quite frankly,I was fired from my last job, due to excessive absences as a result of being an alcoholic. I'm not proud of it . I can only move forward with my new healed attitude and give everything my very best. Do I "come clean" and risk being judged for an ill past ? What thoughts can you share ? Thanks.
