Nausea!

For the love of Pete when does the nausea stop? I had no nausea up to week 8, weeks 8-11 were pretty much hell! And now I'm 12+4 and I still feel nauseous all the time.  Half the time I wouldn't even describe it as actual nausea, just a constant uncomfortable feeling. For any of you who have been through this before did your nausea ever NOT go away?
