If I took an Ambiem yesterday two blocks from my house. Ended up in a car accident. the pill was taken at 12:10, the police officer showed up at 12:20 and had me at the hospital taking my blood by 1:00pm. I am a Grastic Bypass Patient, was wondering if any of this mattered. I had just taked the pill when the college student plowed into my car. still my fault, my brakes failed but don t want to be charged for Ambien DUI that BTW, the GSP never saw the bottle, they were down mu pants. he was baising this off a 2010 Ambien DUI after my first husband died. so from the time the pill entered my mouth, how long does it takes to get to bloodstream?--I am a Gastric Bypass Patient--2003
