"i was given  nortriptyline by a pain doctor 7 years ago. it did help somewhat with the pain.
however the side effects have been giving me problems ever since. i have problems concentrating but worse than that i daydream constantly.  i can&#039;t shut it off. it lasts for hours. 
it is like it turned on a daydreaming switch in my brain and i can&#039;t shut it off. i went off of it expecting it to stop. it never has. it gets more unmanageable. i do not know what to do."
