What can u do to help me sleep and stop medication when I've taken it this long? The amount of dosage taken by your friend is too much and must have required medical attention. I woke up in a stripped room no curtains no bed linens and under constant observation. I'm worried that perhaps I have caused damage to my liver; as I know how damaging acetaminophen can be to the liver. Thanks cbright Sunday, November 10th, My friend literally right in front of me took 2 10mg ambiens and then about thirty minutes later she took 4 more.. I never intended to be with a drug addicted individual and worry that one night he will not wake up.
