"i am 5&#039;2 and 210lbs as of yesterday. i have been taking phentermine 15mg for 30 days only. today is my 2nd day and i have only experienced dry mouth and a little more energy. i have read that people have a lot more energy and don&#039;t think about eating. well yesterday i took the 1st pill at 5.55am and i was hungry by 10.30am and sleepy again by 12noon. i tried taking a nap around 7 but couldn&#039;t get to sleep. went to bed around 11.30pm slept fine. i am hoping to lose 65lbs but i will settle for 55lbs. i just wish the doctor would have started me on a higher dosage. i am drinking a lot of water and i plan on working out on the wiifit for 1 hour a day. i will write back in 2 weeks if i lose any weight."
