The question is really for yourself...have you got a problem or was it a one-off error of judgement? Would you like some "error of judgement" waivers to help you whilst controlling?
Seriously.....be honest....it was a silly mistake....case over!
Remember that the controller limits are a fraction of the drink&drive limits; however I am not aware of a single controller anywhere that has ever been tested, nor am I aware of any realistic mechanism or procedure to implement such testing outside office hours.
