Oh yeah, with this baby, MS started at 5 weeks STRONG. I did end up in the ER for dehydration (3 iv bags!) and diagnosed with Hypermesis, so it can get ugly quick! I am on Zofran, twice a day to keep me sane. It doesn't always help, I am still puking 1-2 times a day, but it's a relief from puking 4 times + a day. Some days i get lucky and don't puke, but I definitely have that hangover feeling all day. Sip on water. Snack on fruits that contain lots of water (watermelon, oranges - plump fruit) and veggies with high water content (cucumber, celery, lemon) and sip water slowly all day. I get SO gaggy with water, that if I take a big gulp, I immediately have to go barf. Avoid caffeine as it counteracts with staying hydrated. I found soft foods to work the best (oatmeal, soups, mashed potatoes) since if I DO have to puke, it's way easier than trying to barf up meat or hard pieces of food. Typing this is already making me sick LOL Just hang in there and listen to your body! I found mixing cranberry juice w/water and ice was heaven sent.
