Do you mean serious nausea? I have bial reflux among other things and I get very sick from it but I take an anti-nausea medication called Zofran and it works wonders. It's a little steap in price but it's worth it because I get my day back and it works very quickly... I think it also stops me from vomiting, which is good too. I'm not sure what you have nausea from but I swear by this medication. I only get nauseated in the morning, some mornings are so bad that when I get up before I do anything I run and take the medication and by the time I'm dressed I'm better... some medications are miracles.
