"i started phentermine end of october of 2015 and ran on my treadmill 2x a day. i got hurt and wasn&#039;t able to workout for about 2 months. it is now may 2016 and i only take phentermine every other day and i lift weights 2x a day and i have went from 227lbs. xl shirts, and a size 18/20 in pants to now 166lbs. medium shirts, and a size 10 in pants. i only drink water unless we go to the movies i&#039;ll share a sprite with my daughter. drink smooties and eat a nutri grain bar for breakfast. skip lunch and eat dinner with my kids before 6 most of the time. i love it!! i&#039;m also on a anti depressant that makes me gain weight so i&#039;m doing pretty good at keeping it off and losing more."
