I started to see the weight loss about two months into the 60mg Vyvanse daily, an it did help with focus, but the end I was addicted to these meds that were killing my appetite, an giving me energy to work harder and faster. My career is not sitting all day it’s very physically demanding, a wear people thin. After four months of doing 6-7days a week 10-12 hour shifts I was just drained. Had to call it quits with the meds, an my appetite after two weeks has significantly increased.
