Mellebacca I am so sorry. Like others, I was keeping all my digits crossed for you. What a heartbreaking thing for you and your lovely family. Life can be so unfair. You have always been so supportive to everyone else on this thread. 
StayClosePooky Welcome. I am sorry that you are suffering. Here is my normal spiel, which may be familiar if you have read through part of the thread, and which I hope is useful for you. Are you on any anti emetics? How are the liquids staying down? Do they say you are in danger of dehydration? Things do get a lot better for most sufferers somewhere between weeks 15 and 21. Even the unlucky minority who suffer throughout almost never feel as bad later on as they do in the early stages. A good anti-acid can make a big difference. 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 notice of their measurement of ketones. They are available from any chemists, as it might be a good idea to get them quickly, or online.
