Dui with no breath or blood test?

I was arrested for dui in my apartment complex parking lot. I did not take the breath test and was not charged for refusal cause I was on private property. I was asleep when the officer arrived, my key I believe was in the ignition my chair was layed back i was in my pj's. sleeping. i did some of the field test but then said i did not want to finish because i was very sleepy i had just woke up. What are the chances i gan get this dimissed.
