Does anyone know how long the withdrawel symptoms last? I feel like I am crazy.. it has been over a year. I am 30lbs overweight and barely have energy to walk to the mailbox. I am a runner/cyclist/mt biker/backpacker.. what is wrong with me? I was only on the drug for 5-6 months before I weaned myself off of it... I was really sick the first few months.. but the symptoms have changed.. not gotten better. Is this all in my head now?
