"i have been taking belviq for 3 weeks and have lost 3 lbs so far. no headaches but i get the chills and my body is very achy, i feel like i have the flu. i crave everything! i don&#039;t think i&#039;ve eaten this much in years! i am also very tired, i want to take a nap all day! i will finish the bottle but for $83, i need to see more results."
