Bupropion / naltrexone

"Well I've been taking this med for a little over a month now. I will say the first night I took it I did suffer insomnia but only for one night. Now that I'm on the full dosage for about 2 weeks now I am noticing more of a nausea feeling for the past few days. I've lost about 13lbs so it does works for me. However I don't believe I'll be taking for too much longer due to the nausea feeling. 
FYI - If you eat any grease or fried foods you will definitely feel the affects. It does force you to think about what you are eating and how it affects you."
