"i started at 25 mg for a week then went up to to 50 mg. started losing weight right away. i started at 195. lost 10 pounds the first month. started in june now it&#039;s sept and i weigh 170.  after 2 and 1/2 months the doc raised it to 100mg.  and now it doesn&#039;t seem to be working as well. she raised it again to 150mg so i&#039;ll see how that works out . i still want to lose 20 more pounds. my insurance didn&#039;t pay for it but i did find a coupon on line and it saved me aot."
