I have been taking 10/2 mg of amitriptyline perphenazine twice a day for about a year . My Dr wants me off of it but offers no concrete ideas on how to do this. Can the combination tablets be split? What is the safest way to accomplish this goal? I also right now take .25 mg of ativan three times a day and 25 mg of limictal once a day. He wants me to go up on the limictal and off ativan also
