"when prescribed, i really didn&#039;t think this was going to work. i have pretty much been overweight my entire life. my doctor reccomend i take phentermine, mainly because diabetes was in my family history. december 31st, weighing 263, i began to take half of a 37.5 tablet. the first day, i was super dizzy for the first few hours. but i never felt that sensation again. i haven&#039;t really felt any symptoms related to the pill. today i went in for my weigh in, and i weighed 246, so a totally lose of 17 pounds in 42 days. although i wish it were a larger weight loss, i do have to take into consideration that i haven&#039;t really exercises. but my diet has changed radically. i would recommend to give it a chance. you never know what could happen."
