"i was prescribed this to lose weight but also to help my diabetes (type 2). in 9 weeks, i have lost 20 lbs on the 7.5mg dosage. i have cut my nighttime lantus usage from 28 units to 7 units, and anticipate being able to stop the lantus entirely within the next week or so. i have lost weight before on my own, but not to this extent, and not with these results with my diabetes medicines. the only side effects i have are an occasional tingling in my feet which the doctor says will go away when i stop the medication, and some dizziness, but i also have that without the medication, so that could just be me. however, the dizziness gets better when i drink more water or eat, so it may be not eating or drinking enough."
