Nortriptyline
"I started having episodic migraines when I was 8, and it turned into chronic migraine when I was 16 (I'm 18 now). Untreated, I usually have a migraine every day. After playing with a few different treatment options, my doctor put me on Pamelor. 50mg for the first two months, and then 100mg for the second two. Almost as soon as I started taking it, I started experiencing the adverse side effects. Dry mouth, light-headedness, exhausted 24/7. But the worst were the nightmares. Vivid, every night. I would wake up screaming. I stopped the medicine two weeks ago, but the nightmares still haven't stopped. And the medicine made absolutely no difference in my migraines. Still had them every day."
