Nortriptyline
"I titrated up over two months, 10 mg at a time until I reached 50 mg.  The side effects for me were:  bad dreams, increased appetite, tiredness, heartburn, decreased sex drive, and sadness.  I began taking the medicine at 7 PM and that eliminated the bad dreams.  However, the medicine made me feel depressed.  I would feel sad and start crying for no reason.  This was all in the first 2 months and then the side effects went away.  I have been at 50 mg for almost 3 months now and I feel normal!  While it was hard for me in the first few months, I stuck with it and sure enough the side effects went away.  



Unfortunately, I’ve been getting more migraines recently, and so I’m instructed to titrate up to 90 mg...  So I'm not sure if it works yet"
