The rest of the story is that I took one ambien and thought I was going to bed but blacked out and was kind of awake and took another ambien then was still up then took another and another and another without knowing it. I think I took like 90 mg. And then I remember trying to get into my bedroom but these weird spider webs that were really strong were blocking my door so i couldn't get in (I think in reality I was pulling instead of pushing. So i went around the apartment looking for my roommate to ask him what was up with the spider webs (I was completely psychotic at this point) but I couldn't find him and I think that's when I took the drive. Thank goodness I didn't crash. Then my boyfriend told me the next day that he got a call from my roommate that night and that my roommate found me wandering around the parking lot and brought me in and gave me some water and found his number in my phone and called him. I don't remember that part at all. I was fine the next day but it was a scary ordeal. It can be a powerful drug! Definitely only take it when you're about to hit the pillow!
