I have taken Tydenal PM, I did not read all the directions and took them for a short time. I did not ask my doctor about taking this. Now I read that it is harmful. Once I stop will be ok. I know my doctor is going to give me a talking when he knows. I have to tell him today. I am worried I m having pains in my legs. I just stopped them. Can I be reversed if I stopped in time. I had a test for my liver and he wants to see me asap to talk to me about my test. Thank You . I would like to keep this from any one else to see this. or hear about it. this is Confidential..............
