"i talked to my dr about my struggle of dieting and exercising alone not helping me lose a pound! so he prescribed me a month and a half only 45 pills of phentermine 37.5 the first day i was so dumb to not read the label but only the papers from the pharmacy that said to take one in the morning and another later that day so i took 2 that day and i did not sleep that whole day night till the very next night at around 3am and woke up @ 7 couldn&#039;t go back to sleep. the 2nd day i did take only 1 and i&#039;m good now! lost 5lbs the first 5days."
