Can I get a reduced sentence on 2nd DUI for having mental illness?

The sentencing of my first DUI offense from late October 2011 was completed satisfactorily. On 4/8/17 I was arrested and temporarily detained for suspicion of DUI. I submitted a blood sample to law enforcement; I don't know what my BAC was yet; I have not yet received any charges filed from the DA, but law enforcement confiscated my driver license and gave me a temporary license that expires in 30 days from the incident. My driver license was in good standing at time of arrest, my auto registration and insurance were current, there was no collision, no injuries .....I have a long documented history of "major depressive disorder". I currently take medication for my illness. I also suspect that a recent med adjustment ordered by my physician may have contributed to aggravating my mental condition just before the recent arrest.
