RK2019 Welcome. As Whatsnext11 says, nobody wants to be here, but everyone is very supportive. That debiliating degree of sickness is not normal. Too many nurses and some midwives do confuse Hyperemsis and normal pregnancy sickness. Do ask for some meds from the midwife. If she refuses ask a doctor. Emphasize that you are unable to do anything. Don't despair,most people get relief between weeks 14 and 20. Even the unlucky minority who suffer throughout almost never feel as ill later on as they do in the early weeks. I have put some generic advice below for both in case it helps.
A good anti-acid can make a big difference. Try not to fret too much about the baby, they are effective parasites and tend to take all the nourishment, which is one of the reasons you feel so bad. So long as you can keep reasonably hydrated, they are unlikely to suffer. Some drinks and foods of a sort that have helped others: flat full sugar coke, ice lollies, the juice of tinned fruit, Lucozade, fizzy water, Elderflower water, Robinson's fruit drinks, fizzy orange, lemonade, Dr Pepper, Elderflower coridal and tonic water (eallison's tipple), 7Up, Iron Bru, soda water, ice cubes, chocolate milkshakes (maybe soya), cocoanut milk, orange squash and sips of orange juice if not too acid. Some foods of a sort: nibbles of chips and crisps, baked potatoes, cuppa soup, cheap ice cream, tinned fruit, slices of melon and mango, Scotch pancakes and biscuits. It might be worth investing in some kesostix if you don't have them already as while they are not the best test of dehydration, hospitals do take them seriously. Otherwise, watch out for inelestic skin, ie skin that doesn't spring back when pulled, dark urine, headache, etc.
CarolineLouisa Talking of names, what a lovely eighteenth century name. Welcome, as surely I would have noticed the name if you had posted before. As Whatsnext11 says, if the meds are not working so well, don't hesitate to ask for more or an addition. I hope some of the above advice for RK2019 might be useful for you.
Melleebacca Again, wise words. How are things?
