Since you refused to take the breath test, you need to (or better yet your lawyer) file a request for an administrative hearing within 10 days of your arrest or your license will be suspended for 12 months with no driving privileges. As to getting your DUI dismissed, more information would be needed to answer that question. Please feel free to contact me at 404-812-4305 if you would like to discuss your case in detail.
If you cannot afford a lawyer then apply for a public defender when you get to court.
That being said, since you blew over a .08 you need to follow the instructions on the back of the DPS 1205 form and send in a letter requesting an administrative hearing, along with $150.00, within 10 business days of your arrest or your license will automatically be suspended.
With a breath test that high you will need a lawyer if you want any chance of getting your DUI reduced. Being sorry and completing a clinical evaluation is not going to get you a reduction. Ask for a public defender if you can't afford to hire your own lawyer.
