"prescribed phentermine 37.5 mg after struggling to lose weight. i am 27 years old, 5 foot 6 &amp; weighed 227 lbs. as i am getting married &amp; will hopefully be starting a family next year, i wanted to look/feel my best and be healthy. i took my 1st full pill around 7 am on 10/8 &amp; did feel extra energy all day. honest to god, i did not feel hungry once. i ate a small breakfast &amp; my fiance had to remind me to make something for lunch. when i eat, i eat a much smaller portion. amazing how it feels to not be focusing your whole day on food!! i have had zero negative side effects (i am on my 3rd day taking a full pill in the am) - no dry mouth, no insomnia, no mood swings, nothing. weighed myself this morning: down to 218.6. almost 9 lbs in 3 days."
