I went through horrible lows for about 6 weeks after quitting. I waited until I had 30 days sober before I went to my DR. I didn't want to seek medical help for anxiety from detoxing. I knew much of what I call the crazies would subside. If I felt that my symptons were life threatening I would have sought help immmediately. This is my third time quitting in 30 years. I had gone through it before. She did prescribe me a anxiety med. I took them for about 5 weeks. Now I am just on coffee and nicotine. I need to cut the smokes.
