Fruitloop84 and Tropicasquirrel Welcome. Do ask for meds from the doctor. Below is my spiel that I hope will help you both. . Most sufferers find that they improve a lot at some point between weeks 14 and 20. 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, and Robinson's fruit drinks. I'll add Beaopo's Rubicon sparkling mango drink. 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. Someone recommended a wonderful drink, recently, which I said I would add to the list and - stupid Mother Hen! - I've lost the reference!
TropicalSquirrel There is a grey area between Hyperemesis and bad pregnancy sickness, with one merging into the other. It certainly sounds as if you are suffering badly. As you are outside the UK, I am not sure what brand names they call the meds where you are.
Fruitloop34 I' will add your date to the list. I am glad you are getting a sympathetic hearing!
DeadDoorPost Of course - twice was really hard going! Thanks again for encouraging everyone currently suffering.
Anya212 That soun ds like a really good tip about eating slowly, in installments.
PhotoMum4 I to am in awe of how teachers manage. I'll add your date. On what you and Anya212 say about your husbands trying to find a solution -I think that males react to all problems like that - they want to find a solution, that is their way of sympathizing. 
doriodiva How many weeks are you? Might it be hormoanl surge?
bunhead34 I am glad you have got it for a bit. The Pregnancy Sickness Support number on 024 76382020 is really good for advice on obtaining meds.
Funkypolar It is very lonely. I do hope you get some relief soon.
Waves to Beapo and everyone.
