I have been prescribed the medication called nortriptyline 10 mg because I have constant headaches and have not taken it yet. I have this fear of what or how it is going to react on me. Has anyone ever used this before for this reason? I have headaches every day and use excedrin. Back of neck along side of head on one side. Mostly when I lay down and then get up or wake up with one. What is the feeling on this medication. I take quite a few meds for diabetes and etc. Metformin, fenofibrate, simvastatin, glipizide, exedrin on a daily basis. He wants me to take one pill 1/2 hour before bedtime.Have had the meds for months now and just cant seem to get myself to do it
