"howdy, i had gastric sleeve surgery on 09/11/2015 (starting weight 506). i lost 82 lbs in just 6 months. from that point on it&#039;s only been about 10 lbs every 3-4 months. my last visit to the dr. was on 03/20/2017 at that time i weighed 395 lbs. he then put me phentermine 37.5. i take half a pill at 8 am and then another half at 2 pm. this pill is great at stopping the cravings i would have every 2 hours. now i am not full of energy, but i&#039;m not as tired as i normally am. the only side effect so far is dry mouth. i think this is going to work i&#039;m excited to see how much i&#039;ve lost in a month. keep you posted :)"
