Good advice and it just dawned on me that I should have went ahead and gone to the emergency room. My blood pressure was high, I took it at home and that's one of the reasons I decided to go. I'm certain my blood test will come back negative.
I would not be so confident. Ambien is not part of the typical drug panel but they may very well do more thorough testing for law enforcement purposes and if they test for Ambien it will most likely show up. I wouldn't worry about the other medications (anti-depressants don't typically cause impairment) but Ambien is a controlled substance that is known to cause impairment. If your blood test is positive they have to also prove that you were impaired, not only that you had a drug in your system, but the fact that they saw you swirving may be enough to prove that.
Hopefully, if you get a good lawyer, the charges may be dropped or your lawyer can negotiate a good plea agreement.
