bex557 Welcome. Much sympathy. What meds are you on? There are several they can try if they don't work. Try not to be too anxious about being admitted for fluids as it will help you a lot, but here are some tips below about drinks etc. Everyone is very supportive on here. Some sufferers do continue to get worse before they get better some way after 14 weeks. ere is my normal spiel, which I hope will help. Most sufferers find that they improve a lot at some point between weeks 14 and 20. Even those who are unlucky enough to suffer throughout generally are not as ill later on as they are in the first part. A good anti acid can make a surprising difference to the sickness. Kesostix are worth buying online or from a chemists, as while they aren't they best test of dehydration, hospitals take them seriously. Some drinks that have helped others: full sugar flat coke, ice lollies, the juice of tinned fruit, Lucozade, apple juice, Ribina, Dr Pepper, soda water, Elderflower water, tonic water, ice cubes, Iron Bru, lemonade, lemon squash, orange squash, orange juice (if not too acid), fizzy orange, 7Up, isotonic drinks, sips of chocolate milkshake (maybe soya), fizzy water, apple juice, Robinson's fruit drinks, Rubicon sparkling mango drink , raspberry Lucozade sport and frozen ice cubes of flat Lucozade sport . Foods of a sort include tinned fruit, cuppa soup, nibbles of crisps and chips, cheap ice cream, Scotch pancakes, bagels, slices of melon and mango, grated cheese, baked potatoes, grated cheese, bagels and biscuits.
Dimpous Can you work from home, give the situation we are in?
I do hope you have a better day tomorrow. If not, you might unfortunately need to go back on sick leave. It is a disappointment, but lots of sufferers on here go back to work too soon. I can't improve on what KatieFTMhas said.
KatieFTM I look forward to greeting you in the Pink Castle at the end of the Hyperemesis Horrror Run! 
doritodiva I hope some of the recommened drinks for bex557
might help you. For some reason, sugary drinks often seem to help the nausea best, and at least they are keeping you hydrated, which is most important.
BB2021 I am so sorry that you and Tiff94 have had difficulty in getting Ondansetron.
Jlw2020 The phobia sounds awful. Do ask the doctors if they can recommend a counsellor about such a dismal situation. If not, I am sure that Pregnancy Sickness Support can give advice about getting one on 024 7638 2020.
greatgreengrapes Excellent advice from you and everyone.
Apologies to anyone rudely overlooked.
