"i started phentermine 37.5 on sunday, april 30th 2017. i am 5&#039;6 and 210 lbs. my issue is that a year ago i started a desk job and i packed the pounds on quickly. i have always been a bigger person but i have never been this big. i always thought about food all day - wondering when and what my next snack/meal was going to be.  i should mention that i have been splitting these pills in half per my doctor. the first day i took it  i had lots of energy and no appetite. like a switch flipped in my brain and suddenly i wasn&#039;t thinking about food and my stomach wasn&#039;t growling. i never eat breakfast, just drink my daily coffee and have been eating a fruit cup from lunch and then i eat dinner as usual with the family.  i&#039;ve lost 4 lbs so far!"
