I am suffering from post-concussive syndrome from a fall last December. I am dealing with daily headaches since then. I was put on nortriptyline about 4 weeks ago. It seemed to help with the headaches, but now I don't have any interest in my husband sexually. My psychiatrist told me that this happens in about 40% of people. So, now I have to decide if I want to have a headache everyday or have fun with my husband. Is there any drug out there that would help the headaches, but not take away the sex drive? A side note is that I also have a seizure disorder that was diagnosed at the same time as the fall, so not sure about drug interactions. I am going to call my neurologist, but wondered if anyone else has had this problem.
