I am 23 and weigh 157lbs, and I am the heaviest I have ever been. 2 years ago I weighed 116lbs, then I started nursing school... I have had no time to eat right or exercise but I have been trying with no success. Today I got prescribed phentermine 37.5mg and I have a weigh in, in 30 days. I've been youtubing and reading reviews and I am so excited to get results. I have also seen studies by accredited colleges where the average weight loss was 16lbs over 3 months. I just want to know if, honestly, people are having these amazing results of for example, 20lbs a month? I'm going to diet and exercise daily. Thank you so much!
