Only take them as directed. I OD'd on Ambien, Darvocet, and Vicoden and the darvocet and vicoden wripped a hole in my liver and I can never take anything with acetiminophen (tylenol) again. They were able to fix my liver with 17 doses of this awful medicine call mucamyst that smelled like rotten eggs, I took the medicine over 4.5 days and my body retained the smell for another couple of days-the memory of that smell keeps me from even thinking of alcohol.
