I was given Valium after a car accident, in which I suffered a bad concussion. I do NOT remember most of the night. I take Xanax as needed, and have never lost memory with it, though I have with Klonapin and Lorazepam. The hospital gave this Valium just before releasing me to police, who charged me with DUI. I had 2 drinks and a meal in over 4 hours. I was NOT drunk, or even buzzed! But i remember almost nothing of the time at the station, getting booked. My BAC was .079. With new evidence, I find it was REALLY .049, due to raising BAC levels for 2 hours AFTER finishing last drink.
So, which drug, Valium or Xanax, is more likely to cause loss of memory?
