Topiramate
"I started noticing the weight loss end of January. I weighed at 235 and was down to 220 in a month without trying to diet! Or excise. I was taking 100mg then up to 200, and now 300. I weigh 209 to this date. 26 pounds in 56 days. my mind is foggy, I feel like a zombie, some days I can clean for 5  hours, I have migraines when I've never had them before in my life, my knees are in pain, throat hurts, numb feeling over all my body. Doctors screw you over so be careful. I'm on a vegan diet for the past 5 days will update after another few months to see more of the symptoms and weightloss :)"
