"i just started phendimetrazine yesterday.  i was given the 35mg dose and split the tab in half and took it around 10am. i have taken phentermine in the past and it makes me feel very jittery and gave me headaches.  i didn&#039;t experience this at all with phendimetrazine! i&#039;m so pleased.  i didn&#039;t even think about food and had to force myself to eat lunch.  by dinner time it was starting to wear off so i was able to eat but still not all that hungry.  i went to bed at 10pm and was able to fall right to sleep.  i&#039;m 5&#039;10&quot; and weighed 174lbs at my weigh in yesterday and today i was already down 2 lbs.  i&#039;m hoping to lose 15 lbs total and i feel very optimistic!"
