"started this pill weighing a shocking 300lbs.. day 11 on phentermine 37.5.. so far lost 10lbs currently weighing 290lbs with no excerise, only a very controlled and strict diet... the first 3 days were horrible side effects wise.. i was drinking 12-16 bottles of water 16oz... my  appetite has changed dramatically... just thinking about all the junk food i put in my body for so many years makes me wanna throw up.. aviod drinking coffee i had about 4 coffees on my 4th day and i felt like death was calling my name.. i couldn&#039;t breath and my heart felt like it&#039;s about to pop out of my chest.. also i can&#039;t sleep normal hours anymore it&#039;s 3-5 hours daily.. otherwise it&#039;s an amazing life changing magic pill.."
