... I have been taking bupropion XL for 8 weeks now and I’m still nauseous. I use Dramamine to help with the nausea. I don’t feel it’s working well enough to keep taking it. I started with 150 mg for 3 weeks and didn’t experience nausea. Dr upped it to 300mg. That’s when the nausea stared. Should I keep taking it for-one more month?
