"i am 59 and about 40 pounds overweight. on contrave 1 week. i hated the way i felt the first 3-4 days - lightheaded, couldn&#039;t sleep (interesting others felt sleepy) and at times felt jittery. also had a few hot flashes. i pushed through it and still not sleeping well and some nausea at day 7. i can tell it takes my mind off mindless eating and grazing but still pretty much able to eat a good meal. i did lose 2 pounds in 1st week so that is good! i am trying to decide whether to just stay on the 1 a day pill vs stepping up to second pill a day. not sure if side effects will increase that it will be worth it."
