"i have started contrave off and on for over 8 months now. when i was taking it both morning and evening a did notice the weight loss. my body seemed to just release whatever i ate via bowel movements. i was losing weight. it is hard in the beginning letting the meds get into your system, the dizziness, headaches, moodiness and nauseous feelings did occur with me. i just started back again yesterday. although it is effective, getting passed the side effects is why i keep stopping."
