"on fourth week. beyond impressed. snacking between meals gone. hugely diminished need/desire for food, seem to seek healthier food. biggest surprise is it has eliminated any desire for a nice cold beer (my weakness). past diet experiences used smaller serving approach but almost eat the plate; with belviq using smaller portions but can only eat 1/3 to 1/2. side effects - first day headache was major - so challenging that i would have stopped the medicine if it didn&#039;t disappear - it was gone on day 2.. feel empowered to finally succeed. goal is to lose 25%.  down 2 notches on belt, feeling better and more committed everyday. starting weight 263 - first weigh in end of next week."
