migraine prevention
"I've had chronic headaches for 4-5 years and was treating symptoms with OTC meds which eventually became ineffective. Started having severe migraines about once a week for which I finally sought a more permanent treatment. Had some undesirable side effects to a few of the initial prescriptions. Hair loss, nausea, insomnia, etc. I had a rough start with Nortriptyline. As I increased the dosage I experienced prolonged drowsiness and some constipation. After a few weeks the symptoms decreased and my head aches stopped being a daily occurrence. I have had a few migraines since starting but these have also become less frequent. Maybe from once a week to once a month now. Hoping this works for me long-term and doesn't become ineffective."
