I would agree with Attorney Lewis, you need to speak with an attorney immediately. You should be facing at least a level 7 felony, which should be presumptive probation if you have a relatively clean criminal history. Contact an experience criminal defense attorney immediately.
You are facing very serious matters, first the criminal charge against you for the DUI, and the potential driver's license suspension against you for the DUI. These are two separate cases that arise from you being charged with DUI. Contact an attorney immediately. Attorney's fees range from $1000 to $10000 for DUI representation, so I advise you speak with a few, and find someone you are comfortable with, and can afford.
I would agree with Attorney Lewis, there is a good possibility you will be charged, but if your case is in the Municipal Court things often take a while to be charged because of the limited resources, and high caseload the court has. Hope this is of some help, I would recommend contacting an attorney to discuss this in more detail though.
