Phentermine
"I started February 3rd of 2016, so I have been taking this medication for 5 weeks.  I am 21, 5'2 and started at 259 lbs.   It has been five weeks, but I didn't take the medicine consistently or eat right during the third week due to a passing in the family.  I also haven't exercised at all due to the passing of my grandpa and I started my school semester when I first got the prescription. I do plan on adding exercise into my routine, but just by eating less and trying to eat better I have lost 26 lbs in a month and a half! I'm at 233. I have went from a size 18 pants being TIGHT to a size 14 pants fitting perfectly. There is a noticeable difference and only side effects are headaches and dizziness, but after water and Tylenol I'm fine! :)"
