obesity
"It takes a while to kick in, and you HAVE to gradually increase your dosage - like, start at 25mg twice a day, then every 2 weeks, 25 mg more - gradually increase to the max dosage your doc wants you on. Otherwise the more negative side effects will be more pronounced. I am on this medication for migraines, and the weight loss is a "side effect." It took about 6 months before I saw any weight loss at all, so I was frustrated at first, though the migraines did start to subside a bit. Now, I've been on it a year, and I've gone from 235 lbs. to 205 lbs. without trying at all. Like, I'm not exercising any more than I was, I haven't been dieting at all that I'm aware of - I just don't crave food like I used to. Headaches better too."
