"i started belviq after coming off of phentermine and i have also had gastric sleeve weight loss surgery 17 months ago.  the first 2 days i was so exhausted and chilled i couldn&#039;t hardly move.  it has helped decrease hunger and i eat less now but haven&#039;t lost any wt still maintaining a 131 lbs weight loss but need to lose more.  but last night i noticed i was producing milk.  i have now read up that can be a side effect i go to my gyn tomorrow and will know more but i&#039;m pretty freaked out!"
