Hello, I really would be grateful for help. My Father who is 67 years old and takes xanax,and Morphine. He has been sleeping at least 18 hours a day and when he is awake he sits and falls asleep,wakes up,falls asleep,Falls a slleep while someone is talking to him. He has been stumbleing around and his talking don t always make sense. He has been this way for about 4 days now. I believe it is from too much xanax. He says he don t remember things either. could this be too much xanax or overdoseing ?
