Mirabel
I feel like a complete fraud as I have not had a hospital admmission .... Think I'm just weak and not very good at handling it to be honest
mirabel .... because the health care for HG is SO patchy, having a hospital admission or not is not a sign of how ill or not you are. Besides, some people get appalling nausea which completely sends their life off-track but never actually vomit. Comparison doesn't work with HG/ severe nausea and vomitting.
It is clear that you are really ill and struggling, and that is normal when you get this ill in pregnancy. No one is good at handling this; you're probably as good or bad as anyone else!
At the worst times, and you are in the worst now, most people think they can't get through. Few people are brave. It just comes down to getting through the day; through the next few hours; sometimes to just getting through the next few minutes.
Please don't beat yoruself up. You're ill, maybe iller than you've ever been; you'll only know how ill when you look back.
We're here to listen. It doesn't help much when what you need is a day Without Feeling Ill; but post whenever you need to 
baarmee congratulations and commiserations!
Do take the cyclizine, 3 a day. If you can, get some vitamin B6 to take with it, it's supposed to help. Cyclizine takes a few days to build up in the system and you know what's coming
so it's unlikely to get better rather than worse.
Have you got some ketostix?
