"have taken contrave 1 1/2 years. the first year i lost 45 lbs.  the last 6 months have gained back 20lbs. the first month i will admit i had headaches. i almost quit. glad i did not!! i experienced constipation. i needed more water and fiber. i really watched my fats and carbs. lately i&#039;ve not done as well with sweats and the fats. i need to be more consistent. i also need to add more exercise. i walk on treadmill but need more cardio. all in all happy but need to be stronger for me."
