Bupropion / naltrexone
"I've been on Contrave for right at one month.  The first week and a half I experienced extreme dry mouth, but easily fixed by drinking lots of water.  After first week, I also started with constipation.  Colace rectified the problem, but working with dr for a better solution.  Around third week, I started experiencing the mild headaches.  Mild as in I knew it was there, but it didn't interfere with my day.  

I'm feeling great!  My appetite has decreased significantly, and the joy I get from eating (which is what caused the problem in the first place) has diminished.  I have the energy to get up and move throughout the day.  I've lost 10 pounds, most of which came off the last week.  Hoping that means it will start coming off quickly."
