Hiya frillypig and sorry to see you've had to join us, though congrats on the pregnancy.
Okay, with HG the big danger is dehydration. (Followed by the fact your life gets put on hold for a while and by the sheer misery of it). You can monitor your own dehydratoin levels with Ketostix, cheap little sticks you buy from boots or another chemists, or you can order them from Amazon. You just pee on them and then check the colour against the colours on the container tub. if it's deep burgundy/purple, you need to get advice immediately, probably from a holiday.
About meds, YES THERE ARE. What has your doctor given you so far? If it's cyclizine and vit B6, these are the first line meds. they do build up a bit over a day or two I believe, but they are pretty mild and a lot of people have to go for something stronger.
By the way, best practice recommendations now say that treatment of HG shoudl begin early to soften the worst effects of the disease, in most cases. So you should be getting meds now and you should be getting strong enough meds to actively help you.
This is a website that has some excellent information on HG generally and on meds: Pregnancy Sickness Support and this is the list of meds commonly given: Treatments. They also have a list of coping strategies under Get Help and some eating advice. Ginger is plain useless for hg - I've looked into some research articles and not one woman with HG has found ginger helpful.
Okay, about your doctor. The national Clinical Guidelines make it clear that management of HG should have these goals:
To reduce nausea and vomiting
To reduce time off work and other lifestyle disruptions caused by symptoms
To prevent complications
Have a look at the site: cks.nice.org.uk/nauseavomiting-in-pregnancy#!diagnosissub All doctors are supposed to follow these guidelines. They also lay out which drugs are supposed to be used.
So yes, there's more than just the two you're on at the moment and things -can- be done =) If your doctor keeps on not taking it seriously then there's a possibility of help from the Preg Sickness support too, but hopefully your own doc will be a bit more helpful if you can go in again.
Is there any chance of getting help with childcare? if it gets really bad it's simply impossible to look after children, though hopefully it won't get so bad. But if you can, rest, rest and rest. It really helps.
