Unless you like jail time, not guilty. What can you do? Hire an attorney, unless you know how to effectively represent yourself in court against a professional prosecutor intending to convict. No amount of free 'tips and hints' from here or anywhere else are going to effectively help you in your defense, other than the advice to exercise the 5th Amendment right to not talk to anyone except an attorney about the case. Most police and prosecutors will happily tell you that 95% of people convict themselves by trying to be 'helpful and cooperative', either during initial contact, questioning, interview or interrogation.
Keep in mind a little free advice: When you are arrested and charged with DUI, whether alcohol or drugs, then upon release from jail or booking you were given documents that included a notice that you have only ten days to file a request with DMV for a hearing on an appeal of an automatic one-year suspension of your license imposed by DMV. That is separate and runs consecutively with any suspension that may be imposed by the court. Contact DMV and do so, timely, then appear at your scheduled DMV hearing and present any supporting evidence and testimony. If you don't know how to do these things, then hire an attorney that does. If serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me.
