I used to take 100 mg of it years ago and then was weaned off after 1 year of no migraines. Now they are back and range from full force with nausea/photophobia/vision changes to a dull omnipresent ache that is always threatening to become a full-fledged migraine. I've had a headache for over a month straight every day and sometimes waking up at night from it, but no insurance until February to start on anything again. I remember the Topamax worked but I forget how it made me feel. Does anyone take it and have any problems working? Any trouble with your memory? I'm not looking for medical advice as I've been on it before and just reread through the side effects, just looking for personal experience with using it daily while being in such an intensive field like nursing. Thanks in advance.
