"fastin is an excellent dietary supplement for me. in the morning, right as i wake up, i take the little guy. the pill tastes like what i would imagine what baking soda would, but oh well, i am not sucking on it. it takes about 20-30 to give the first kick. that kick is the rush that says &quot;i need to get moving or i need to get to the gym.&quot; the first time i took the pill i did get a little jittery and nauseous but once i started working out and drank water i started to feel fine. about an hour in i hit phase 2. phase 2 is the spunk and mood booster. i feel awesome and amazing like i know what i am working for. again, first day i felt a little dizzy and euphoric. then there is phase 3 the come down. drink water and eat a solid. i lost 100lbs."
