Nortriptyline
"I've been on nortriptyline for close to 15 years now for migraine treatments after a significant head injury. Before being put on the medicineI'd get migraines that would put me out for days at a time. After starting out a low dose it helped control my migraines and has continued to do so over the past 15 or so years (though with increased dosage). The most common side effects have been drowsiness, dry mouth, quivers in my hands along with adverse reaction to prolonged periods of being in the sun. I've also put on a few pounds over the past few years, but that may be the result of moving from an active job to a more sedentary one and not the medication. Overall nortriptyline has been great at controlling my migraines without too many negatives."
