"okay, so, i never thought i&#039;d ever write one of these reviews, but, here goes. i asked my doctor about phentermine after having a very hard time losing weight (under his monitoring) for 4 years. i&#039;m young, only 27 and 5&#039;4&quot;, so it shouldn&#039;t be this hard. i started on 15mg back in may of 2015 clocking in at 210lbs . with complete diet change, and moderate/high level exercise 3x a week, i now weigh 145lbs. i feel incredible and the effects of the phentermine act mostly like a glorified appetite suppressant. it doesn&#039;t really do much itself, but it does enough to keep me aware and on point. maybe that&#039;s all i needed? no side effects at all. then again, 15mg is less than half a normal dosage. i love it. 10/15 more pounds to my goal!"
