"So, I started Belviq a few weeks ago. I sometimes had headaches but nothing a few advil wouldn't cure. It took about 2 weeks for the medicine to start working. You have to be patient and remember this is a serotonin drug, it affects the serotonin in your brain which controls hunger and feeling of fullness. Its just like when you take medicine for depression, anxiety, OCD, they take time to work.
  I was very surprised I did not have any side effects to speak of because I am super sensitive to medication. I am less hungry and I do not find myself thinking of food all the time. I have lost 4 pounds thus far and am hoping to continue losing weight."
