"today marks 1 month on belviq and freedom from 24 pounds of fat! i am 5 feet 5 inches tall, 50 year old female and started at 220 lbs. the first 24 pounds came off in the first 3 weeks.  the weight loss seems to have slowed down this past week but i&#039;m ok with that as i figured i could not continue to lose at that rapid pace.  as for side effects, i did have a slight headache for the first two days but nothing tylenol didn&#039;t handle quickly.  the other issue i&#039;m having is a very annoying cough.  i read where that is a side effect for people with diabetes, which i do not have.  i am assuming the cough is from the pills but it is possible that i have a cold or allergy."
