"hello all, i started taking this diet supplement on january 1,2017 and i was so excited and determined to do what it takes to be successful.  i was  prescribed  phentermine 37.5mg and took the whole pill daily earlier morning with water and 30 minutes before breakfast. i would drink plenty of water throughout the day and  would only drink a half cup of coffee 2 or times a week. my calorie in take daily was 1300 . and i would exercise 3 or 4 times a week by doing 1 hr of cardio. i would experience mild side effects such as lack of sleep,  mood swings, light headaches and dry mouth. by drinking plenty of water really helped a lot.  what really helped me a lot was keeping a  daily  diary  and writing down  everything i ate. i lost 20lbs in 2 months"
