"i have been on topamax since may of 2015 and it is now september 26, 2015. i did take it for migraines and boy did it do its job, i was having them every day and now i get them maybe once a month.  i started at 25mg went up to 50 twice a day and in the beginning of september went to 100mg where i will stay at and stabilize.  weight loss!  well where do i begin!  it has been amazing!  i weighed in on may 15 at 167.5lbs, i am only 5&#039; tall, no inches there lol, and i weighed in september 2nd at 141.8lbs.  it is amazing to me that i have lost 26lbs without diet or exercise.  i have always done yoga and meditation, but not the hardcore kind,  the gentle kind.  i really haven&#039;t changed a thing except for taking topamax."
