Suggest Treatment For Headaches And Nausea Caused Due To Intake Of Victoza

Hi Doctor, I was prescribed victoza for weight loss and did well for the first few weeks. Lost 8 lbs. I then started having side effects. Headaches, nausea etc. I came off the med cold turkey and in 1 week gained all the weight back. I am commited to losing weight and wondering if I should give victoza another go. Will the side effect lessen as my body gets used to the med?
