"i&#039;m a 25 year old female 4&#039;11&quot;. i started taking phentermine on the 21st of this month. my doctor instructed me to take only half a pill the first 7 days and then i would start taking the full pill in the morning. my weight was 155lbs and and i now weigh 146lbs. i have lost 9 lbs in 5 days. my doctor had me cut out all carbs. i drink a protein shake in the morning and at night and i eat a low calorie lunch, with snacks like fruits or veggies in between. i also work out. the first few days on the pill i felt jittery but that&#039;s gone now. i also had headaches, that&#039;s also gone. i do still have dry mouth so i make sure to drink plenty of water. i recommend this pill to anyone. in this short period of time it has already changed my life."
