"today is my first day taking belviq at 5&#039; and 163 lbs. my goal is to lose 40 lbs. my mom tried one of the pills yesterday and felt headache, dry mouth, body aches, and chills for a short while. she noticed her appetite was definitely suppressed. today is my first day taking it (once a day) and i had a couple seconds of chills and thats it, no other side effects. my appetite definitely hasn&#039;t been suppressed but i&#039;m hoping that within a few days, i will see some changes in appetite and some weight loss."
