I went to a neurologist who told me I am depressed. I am generally a very happy person. People have told me that they have never saw a more happy teenager then me.. Anyways, my neurologist told me I should take nortriptyline hcl. She wrote me a pescription for it.. I have read that it causes heart failure and depression. I have been told its an addictive drug. I have a very high pain tolerance, but my headaches can reach a 9 or 10 on my scale of 1 to 10 sometimes... I also don't have very good sleeping patterns anymore because I wake up a lot.. How many people have had problems with this medication? Do you personally believe it is the right one for me? Especially with the side effects?
