Dont risk it. We have probably all driven over the limit unintentionally (following morning etc) in the past so none of us are better than everyone else unless you are strictly teetotal.
Driving whilst disqualified, driving without a licence, driving without insurance plus whatever the reason they actually give you the (unlikely) tug for could mean a very hefty fine, a proper record rather than just driving offences (and possibly jail time if the judge didnt get his leg over that morning), and the prospect of not getting a job/mortgage etc you want/need in the future should be enough to make you cycle to the station and get the train however awkward it actually is. Being banned is meant to be punishment after all.
