"have suffered with back pain for 22 yrs. i&#039;m 60 yrs old now.  started taking nortriptyline 4 days ago. while i know that&#039;s not very long i can say back pain is much better. depression is much better. overall feeling is much better. sleeping better and longer. i have noticed some drowsiness but not a lot. i hope things continue in the direction i&#039;m currently headed. good luck!"
