I don't know what your profession is but I spent my 5 of my 6 yrs in sobriety as a stockbroker - a field I had 18yrs of experience in and recently left. At the end, I had close to 1000 clients, most of whom were wealthy, influential, "important people." I was also the branch manager........managing other brokers.
"Entertaining" was and IS a very regular and important part of the job.
Early in recovery I used a number of half-truths to explain myself. As I grew in my recovery and grew in my maturity I began to get more and more honest. The last 3 or 4 years I just used one line: "I'm a recovered alcoholic and I don't drink anymore. I used to drink quite professionally -haha- but I don't anymore." Not ONE time did being honest ever hurt me. Never lost an account, never got any odd or negative feedback and as a matter of fact, it actually GOT me some extra business....and that was a fairly regular occurrence not something that just happened once or twice.
