Have you gradually increased your dosage? Amitriptyline stopped working for me after 10 mos of working great. I gradually went completely, took a couple months break then start back up gradually, eventually getting to 40-50 mg in split dose (10 mg am, 10 mg mid-day, sometime 10 mg early evening and 20-30 an hour before bed....this works somewhat, never really gone like the first 10 mos of 30 mg at bedtime- good luck
