Getting the charges dropped will depend on the results of the breathalyzer and blood test. I recommend speaking with an experienced DUI attorney in your area. He or she will request discovery and get all the evidence in your case. He or she will also be able to examine the evidence for any errors in the Field Sobriety Tests, or blood samples. This is a very technical process and there can be several arguments and defenses in those types of cases. Good luck.
The likelihood of a favorable outcome increases exponentially with the assistance of an experienced criminal defense attorney on your side. Now is not the time to be penny wise and pound foolish. Use the "Find a lawyer" feature on to find one in your area. Good luck.
You should retain a criminal defense attorney as soon as possible. It is unlikely that anyone will agree to "drop" DUI charges if the evidence is sufficient to proceed. However, an attorney may be able to discuss some diversionary programs that ultimately result in dismissal of your charges. The sooner you retain counsel, the better your chances of a favorable outcome.
A lot more would need to be known. You may be eligible for an alternative disposition to keep your record clean, there may be suppression issues, there may be trial issues, etc. There are many questions needed to be answered. However, they will not simply drop it. You need experienced trial counsel.
Why did the officer stop you in the first place?
A great way to beat a DUI is to challenge the reason for the stop.
How far apart are the breathalyzer readings?
I have seen in Philadelphia, the reading taken only 1 minute apart. However, the Intoxilizer Manual states that the readings should be 2 minutes apart.
