Welcome to HairsprayBabe. Sorry you feel so bad. You have had great advice from Melleebacca, Whatnext11 and GinnyOz already. I so agree with it, do ask for other meds as the Cyclizine isn't working. There are others they can try, and combinations, too. Below is my normal spiel, which repeats some of what others have said about kesostix, etc. You already have discovered ice lollies...
Here is the normal spiel. Don't despair,most people get relief between weeks 14 and 21. Even the unlucky minority who suffer throughout almost never feel as ill later on as they do in the early weeks.
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, scanty dark urine, headache, etc.
Melleebacca Aagh - poor you! A cold, headache and two sick youngsters. I hope the headache isn't a dehydration one, but it sounds as if you think it is? Much symmpathy.
Whatsnext11 Hee Hee about name calling. 
Waves to GinnyOz and everyone.
Watch me cross post.
