"Naltrexone alone can cause nausea. Wellbutrin alone causes nausea and in some cases permanent ringing in the ears.  I highly recommend everyone listen to your body. Nausea is the body's natural reaction to try to rid itself of something bad (viruses, foods, drugs) whatever it may be. This drug is NOT the answer.  Sure you will lose weight, but at what expense....nausea, ringing in the ears, vertigo and dependence on the drug which is very expensive?"
