"i started taking phentermine 37.5mg october 2008, i noticed from the very first pill i had a natural energy. i also felt happy, and the pounds came off. i lost about 6pds a month. i started out 213, and in 6 months with going to the gym 4 times a week doing cardio, i was down to 144pds. that was my lowest weight, i enjoy this pill. phentermine honestly gives me a natural energy to want to work out, and it curbs my appetite even when i am bored.  i don&#039;t take the pill anymore. just don&#039;t drink any caffeine with them and you&#039;ll be okay!"
