"i started my prescription last night. immediately, i was a bit drowsy, somewhat euphoric. i ate 4 hours later &amp; felt ridiculously overly full without overeating. i know it&#039;s not supposed to work for 2+ weeks, but i did have a crazy full feeling for a long time. my insurance covered it, 90 day supply, but with a $150 copay. i printed the savings card from belviq&#039;s website and it covered the $150!! you can use it on top of your insurance, or if you don&#039;t have insurance. it covers a portion. and you can use it for 12 months."
