"i have been on belviq for 8 days now and have lost 6 pounds.  i am using the losing it app to log my food and track my calories which makes it so easy.  my goal is 1200 calories a day but sometimes i just can&#039;t work them all in.  the first couple of days i did have a small nagging headache but i am use to dealing with migraines so it wasn&#039;t a big deal.  the first week there was some tiredness but that seems to leaving me now and i seem to be getting more energy back.  the discount card is a plus since it only cost 75.00 a month to fill.  i am happy with the results so far and look forward to feeling better without the weight."
