your not fucked yet.... first of all they have to give you a sobriety test or a breathalizer test to even give you a citation for drunk and disorderly in public, i have got busted for the same thing you did and it was sooooo easy to get the charge droped, first get a lawyer and plead not guilty. second go to court and tell the judge that the citation that u where issued was illegally issued by no evidence of a breathalizer test. now u only have circumstancial evedince pressented against you and you should get off, ide say a good 90% chance of getting the charges dropped or be proven not guilty. remember the law, innocent until proven guilty WITHOUT A REASONABLE DOUBT!
