I know a former alcoholic and this is his experience not mine.
He quit drinking in 1999. His recovery was slow but by 2003 he wasn't drinking any more. He believed he was in control. One day he gets some really good news and decides to celebrate with friends. He gets drunk and for the next few months struggles with his addiction but manages to stay strong [and clean]. He realized he was still weak and since then hasn't ever touched alcohol because he knows what might happen.
I learned from him that one can't overestimate his control over a substance which he had no control over once. It's always better to be safe than sorry. No need to test yourself even if you are sure you are in control.
