Hi, I have had hyperemesis both my previous pregnancies- both times ending up in hospital for several days just to recover. This time the doctor has put me on medication from the start- it hasnt stopped me being sick but it certainly helps. I had Zofran in both previous pregnancies so was confident that it would be okay this time. Dehydration is worse for you than most meds they will give you, you need to be hydrated to be able to supply what your baby needs. Also if you are feeling really dry and not coping i highly recommend going into the Emergancy department, they will test your urine for ketones and check your bloods for dehydration- if your admitted then you needed to be there, if not they will probably pump some fluid into you via IV and after a few bags you will be surprised how good you will feel. It makes all the difference in the world! I have been in once this pregnancy to get the fluid and the five hours I had to wait were worth it! If you are vomiting more than three times a day and not keeping fluid down go in. otherwise, what has worked for me, or helped alot is keeping something in my stomach- even if all you do is dry crackers- eat! You may vommit but it is important for you to and even if you are going to vomit drink- get the hydralight or powerade - eletralights (spelling) are imperative! ... So i eat constantly- crackers and dry toast, apples - chew them properly, just in case same with celery, i peel them tho... lol... when you get up at night to go to the toilet as we all do at this stage- eat some crackers- before you get out of bed- eat! And more than anything - i have found ecalyptus drops to be a real God send, i suck them to help with the horrible phlegm that i have and it helps to keep me from being sick. Also ice- now this is my biggest friend atm, i even drive through mcdonalds when i am out to get a large cup full of it, just to get fluid into me. Dehydration is what will get to you the most with morning sickness... hope it helps- Sure wish someone had passed this onto me when i was pregnant last time! lol.
