Hi, I took two 50mg tramadol tablets for a bad back, that evening I was very high, the next day I was very depressed, I could not sleep that night on the following days I was anxious, had a high heart rate, shaky hands, felt light headed, sweating at night, felt sick every day, I had two panic attacks, had wierd thoughts, nearly two weeks later I still feel light headed, am I still experiencing the effects of tramadol? Feeling some what better though.
