I was an anesthesiologist for ten years; I was treated for opiate dependence and attended AA for 5 years without anyone knowing about my history. I stopped meetings, and a few years later the addiction returned-- not in the OR where I handled the 'big drugs', but on vacation in the Bahamas at a little market that sold codeine over the counter! I came back to work scared to death, but didn't use... but six months later the voice in my head suggested that 'I am different now-- I could quit, so I am now in control'. This voice was the start of four months of complete craziness-- could have, even should have died... I ended up losing my job, license, career--- and almost my family.
The road back looked impossible back then-- but now it looks like nothing. But one day at a time it came back. I was monitored for over 5 years by the board (after three months residential treatment-- sold our vacation cottage to pay for treatment). After two years I went into residency in psychiatry; three years later I finished residency and now I am a psychiatrist in solo practice, and medical director of a large residential treatment center. It all just happened one day at a time. If I had tried to see the road ahead, I probably would have freaked out and run from it!
Just keep doing the next right thing, and focus on the important things in life-- and the rest will take care of itself.
Good luck!
