Topiramate
"I went on topiramate January 2012 for migraines with positive results. By the end of  2012 I had lost 85lbs, and 7 dress sizes. I had started out at 235lbs and ended up at 150lbs. My dose started out 25mg twice a day, then went up to 50 mg twice a day in two weeks, then was increased to 100mg, twice a day in 3months. At the end of my treatment, my dose was 300mg daily.  I had also lost the ability to form sentences, because I couldn't find words, and was constantly in a fog. That is not good if you're a nurse. Also my short term memory was non existent, also not good for an acute care medical nurse. By the time the side effects became so debilitating, I had to take a short leave of absence to sort out my situation because it affected my job performance. In the end, the medication was discontinued by my doctor and I gained 23lbs of the weight back. I'm not upset because now I have my short term memory back, plus I've returned to work and I'm migraine free.  I'm still better off because I'm still thinner than before I started with topiramate."
