Constant nausea

Does anybody else have constant nausea? Sometimes I get an hour or so break from it, and am able to get up and get things done.. Then BAM!  Back feeling nauseated and on the couch. This is my 3rd, although my youngest is 6 and I feel like I'm starting all over, my first 2 were a breeze! Never sick at all with my first two! I haven't thrown up at all this pregnancy, but literally nauseated all day long! It just sits at the top of my stomach/bottom of my throat. God bless ya baby, and hormones for doing their thing.. Just ready to enjoy being pregnant!
