"i took this one a few years back and lost over 20 pounds in about 3 months. i&#039;d have kept using it but didn&#039;t have the money to keep going to the doctor. some years have passed and i&#039;m back at another doctor who&#039;s giving me tenuate. it&#039;s nothing like i remember with the phentermine. i was probably in better shape my first time around because tenuate just doesn&#039;t seem the same. i don&#039;t have nearly as much energy as i did with phentermine. when i was taking phentermine i was constantly looking for something to do. i was always cleaning and moving furniture when i wasn&#039;t walking to school in the city."
