I must say that since I have been on nortriptyline (2 weeks) my headaches have gotten much better. I still have trouble with lights and noise and doing things that make my brain go back and forth, but as far as being able to cope at work, it has gotten much better. If someone would have just listened to me 10 months ago, it would have been great. But, I am feeling better and that is all that counts. I am only on 10 mgs. and am supposed to go to 20 mgs., but think I will wait. If I can control the headaches with the least amount of drugs, that would be even better.
