LostNames As others say, do ask for other meds. Cyclizine doesn't suit everybody. Also, a good anti-acid makes all the difference. What drinks can you stand? Some that have helped people on here.
Ice lollies, flat full sugar coke, the juice of tinned fruit, ice cubes, soda water, fizzy water, Elderlower Water, Lucoazade, Dr Pepper, fizzy orange, orange squash, orange juice (if not too acid), Lemonade, Robinson's Fruit drinks, Iron Bru and sips of chocolate milk shake, maybe soya. Awful foods seem often to be bearable, like nibbles of crisps and chips, and cheap ice cream, and cuppa soup, Scotch pancakes and tinned fruit, especially peaches. Also, more healthily, baked potatoes and slices of melon andmango. Do invest in kesostix from a chemists to check for the early stages of dehydration.
Kleino Much sympathy. It is hard, as others say, to hold your own with doctors when feeling so ill. Can you get someone to go with you to back you up as an advocate? Sometimes one can hardly speak for fear of being sick - not as if it wouldn't serve some doctors right if you were sick on their shoes. I wonder what this drug is that you only take once a day? Do ask for an anti acid, too.
SassheMonsta How lovely about those flutters! Congratulations.

TwoDrifters That's wonderful. 'It's a lovely day tomorrow, tomorrow is a lovely day...'Best of luck. Do tell us how things went when you can. Nobody should hate you for having reached the legendary Pink Castle at the end of the horrific Hyperemesis journey. You've suffered throughout. 
Sorry so many people feel so bad....Watch me cross post.
