"i have been on belviq for 3 weeks, twice daily. most side affects have gone away except i&#039;m still tired a lot. i started @ 244, i&#039;m now at 230. i walk 2 miles most days of the week and i watch my carb intake.  it has greatly reduced my appetite where i almost forget to eat. i drink lots of water and drink a cup of hot green tea at bedtime."
