I lost about 30 pounds over a year. Topomax did not stop my headaches - it made my imitrex tablets work again. I found the side effect of topomax to be AWFUL. It negatively affected my memory, my ability to express myself and my personality. I would go completely blank when I needed to speak in public. I became quick tempered and generally disagreeable. Eventually, my doctor took me off topomax and started me on depakote. Then I gained 40 lbs in about five months. So I would not advise getting rid of clothes. You may need them on your way back up to a bigger size in the future.
