"in 2008, i took phendimetrazine and along with diet and moderate exercise i lost 40 lbs in 3.5 months. the only side effect i had was occasional constipation when i didn&#039;t drink enough water. i didn&#039;t feel &quot;the energy boost&quot; like i was told i would. i loved it then! after gaining back 15lb (gained weight with pregnancy) and realizing my baby is now close to 3, it&#039;s time to get back into gear. tried diet and exercise by itself with minimal results so i resorted to finding a weight loss clinic. i&#039;ve been on the extended release for 5 days and it seems to be different. it doesn&#039;t seem to suppress my hunger like the first time around. i am still taking it though, i will weigh in on oct. 16 so hopefully i will see results!"
