"i am 56 years old who with severe chronic nerve pain in my neck from herniation at c6-c7 and c4-c5. i opted no surgery and i have had zero quality of life and on bed rest for 4 years.  started pt with pain meds neurotin 600mg and i was slowly able to function in a brain fog but free from strong narcotics. went to amitriptyline 40mg at night slept great but next day brain fog with memory lapses and always tired. now on 10mg nortriptyline i take in the morning because it affects me like a stimulate and hard to sleep at night but been on for a week. i have constipation but i take fiber in water helps. i love been alert with a clear head! so far no pain on 10mg so i won&#039;t increase unless i have pain.  a very livable dose."
