Just an update: I had a lawyer, but we are no longer in contact with each other. Our last correspondence was Friday, and he hasn't responded to any of my phone calls since then. When I told him that I didn't want to go to trial and instead wanted to plea bargain, he stopped responding to my phone calls. Does anyone have any specific suggestions?
By the way, I could be wrong, but I believe the maximum penalty for me is 30 days in jail, $500 fine, substance abuse treatment for 90 days, and loss of license for 120 days. I'm seriously considering not having a lawyer. As long as I convince the judge to drop down from aggravated to un-aggravated, I probably won't have to worry about jail time.
