I have migraines. Topiramate has been a God send for me too. But, I have to watch it. I have kidney stones. I take 50 mg twice a day. Plus, I take propranolol 60mg 3 times a day for migraines and essential tremors. The first two doses I had to cut back. It was kicking me down. Slowing down my heart rate too much. So the doctor told me to adjust to how I felt. I have tried Quilipta but topiramate won. I use ubrelvy 100 mg when I get one. I can't afford the ubrelvy and insurance won't pay much. The Abbvie Patient Assistance Program pays for it. (not sure if I spelled Abbvie correctly). I have had migraines since I was 16. (50 years) Finally found great neurologist. I know your pain.
