"im 20 and im on week 4( 2 pills in the morning and 2 at night) i am 16 pounds down already. i am experiencing mild nausea, but it&#039;s only when i eat certain things. once i throw up, i feel much better. i am trying to include more fruit into my diet to compensate for the food i have been throwing up. i have heard these symptoms don&#039;t last but 2 weeks max. if they last longer than that, i&#039;m going to go back to the 2 pills in the morning and 1 at night since i did good during that. this pill has been great at eliminating my cravings. no constipation or headaches so far."
