Hang in there...I know the nausea sucks. I haven't had twins but have 2 and remember the nausea all too well. I ended up taking Phenergan with my second and that helped and made me very tired. I was nauseous in the evening so I would take the pill and go to bed. It will get better!! Just eat what you crave, don't get too hungry, stay hydrated...you can do it!
