Can i get burglary charge dropped to unlawful entry?

Back in December I was arrested for Burglary and Grand Larceny. I got really sloppy dunk one night and went home to a friends house. I don't exactly remember what happened but apparently I got up in the middle of the night still drunk and walked out with their laptop then walked down the road and walked into ( not broke into ) someone else house and took something from that persons house. Now the first memory that i really have of any of this is me walking down the street. I don't know why i was doing it though. And the next thing i remember is i was standing in someones drive way wandering where i was and then the police showed up guns drawn telling me to get on the ground. I didn't have anything in my possession when they arrested me. I was told by one of the police officers once i got to the station that they found the property that i had taken in the yard about a block or so away from where they found me. Apparently i set it down or something while i was walking. So ultimately they charged me with Grand Larceny and Burglary of a dwelling. Due to what happened I have accepted that i might have some kind of drinking problem and have completely stopped drinking. I'm currently going a church pastor once a week for counseling. I don't have money for an attorney so i have petitioned for a public defender. I had someone tell me that since i don't have a criminal record ( other than a DUI 4 yrs ago ) and i've never been charged with a felony before that the prosecutor could reduce the charges to unlawful entry or something. I just to know if this is true and if so what are my chances of getting them reduced. This happened in Mississippi by the way. Thank you in advance.
