"i&#039;ve used this drug 2x&#039;s. first time i lost about 20 pounds, which was awesome but after prescription ended, i gained most of the weight back even after i swore i&#039;d never do that. 2nd time i used, no real results, guess my body adjusted to the drug. each time i took for approx 4 months. my suggestion, achieve weight loss the old fashioned way, workout and make smarter food choices. track what you eat too. i know that choice isn&#039;t anyones favorite, but its natural and much  better than artificial drugs. this drug causes insomnia, and crazy mood swings, and irrational thoughts and behaviors. do yourself a favor, don&#039;t use this. while the promise of quick weight loss is so tempting, the long term effects outweigh the positives."
