deep breath kali ... like okla says, half yay, half oh no ... you do have our full support cheering you on, if it's confirmed.
saras welcome and congratulations and commiseratoins!
Ok first off, the meds are safe for the baby and for you. Cyclizine is actually pretty mild and the side effects, if you get them, are annoying but there is no long term danger to the baby or yourself. It sounds like you need stronger meds though. One (metoclopramide) does have potential side effects for a few mothers (not the babies) but therés a lot of experience on this thread by now and we can help you
Secondly, can you enlist your husband's support as an advocate for you? when you are very sick like this, its really hard to explain to the doc what it's really like and also, your husband can look up some of the links ill post in a sec. They give you the list of meds commonly used in preg for severe sickness. [[www.pregnancysicknesssupport.org.uk/ This site] is run by survivors of HG and has good info on meds under the Help tab at the top. They also have a retired, very experienced doctor there who you can speak to if need be.
Please ask your husband to look at that link and the others Lucinda put at the top. also, there's some good american forums here with a section just for dads which he may find helpful?
Thirdly, are you able to keep water / liquid down? maybe in the form of ice chips or flat coke or ice lollies. Some people find very hot drinks also bearable, sipped through a straw. Please get some ketostix cheap from the chemist or amazon. You can test your own dehydratoin levels. lucinda explains it well but the dehydratoin is actually more of a danger than the lack of food. Its the dehydration the doctors check for.
Fourthly, the only justified use of Ginger Biscuits with HG women is as ammunition to throw at people's heads who don't realise what it's like. Arrrrrrrg how we hate ginger!!!
