Not a good situation at all to find yourself in. I would never reveal on here my place of work or anything about me in real life for the very reason that some low life would stoop so low as to try and take away a mans livelihood by malice. The DVLA will react to any information they receive, they have too in the name of public safety. Strengthens my case for the DVLA to only accept medicals from your own GP. Chances are he would know of any drug or alcohol dependency thus not taking this kind of malicious information too seriously.
