Nausea/Vomiting
"I started taking ondansetron during my 8th week.  This is my second pregnancy and I literally could not get out of bed always feeling sick from morning to night.  I could not work cook or anything.   While it did help me keep foods down I still felt very sick like i was going to throw up but never did. I thought I could go to work (hairdresser) and I was wrong. I almost passed out, it makes you very drowsy.  I am on my 15th week and I stopped taking it two weeks ago the benefits were not outweighing enough.  Even though I am still sick and have thrown up a couple of times here and there, I stopped taking it.  I feel much better not taking it."
