"i have been taking phentermine since 09/18/08 at 191 pounds.  honestly, i haven&#039;t weighed in yet, but i feel terrific.  my energy level is way high. i&#039;m a 40 year old college professor, and have been used to taking naps before working at night (i would always be grumpy if i missed my naps). since i&#039;m now on phentermine, i am a more positive person, alert, super-alert. i hate washing dishes, pots, and now i have so much energy and willingness to be more in the kitchen and cleaning.  i sit with my son to help him with his homework. now i find time to do stuff instead of &quot;relaxing&quot; or &quot;recharging&quot; my batteries in my bed.  this pill is amazing.  it has changed my lifestyle so far.  i do have some difficulty sleeping and dry mouth, but it&#039;s great."
