"i started taking phentermine due to some weight gain after a spinal fusion i had in april 2014. i can&#039;t do much exercising because i am in pain all the time. i started taking phentermine october 1st 2014. today is my 4th day i have lost 11lbs. i weighed in at 212lbs and today i weighed in at 202lbs. it&#039;s hard to change eating habits but i am doing this so i don&#039;t have to have another surgery. not everybody has the same body make but if you are determined whether you shed the lbs fast or slow this diet pill works. i recommend it to anyone who&#039;s willing to take charge of their life. only you can make that change. only side effect is dry mouth which means you will want to drink a lot of water."
