Bupropion / naltrexone
"I'm 34, started at 168 lbs & am 5 ft tall. Week one I had dizziness & really bad anxiety. Day 3 thru 5 I thought I was going to pass out at work. I can't stay asleep. Week one I lost 2 lbs. I'm on week 2. I increased to 2 pills on Saturday. Earlier today (Monday) my coworkers said I was acting weird & I felt anxious again. I took my 2nd pill at 8 pm. It is now 5:20 am. I woke up at 2:45 feeling dizzy & very anxious like panic attack anxious. I am tired, nauseated and dizzy. I don't see how I'm supposed to go to work. I'm seriously considering going off this medicine. 
Pros: it really did cut out cravings, I eat A LOT less, I drink more water & it's easier to make better choices 
Cons: Anxiety, lightheadedness, dizziness, nausea, insomnia"
