LindSan Welcome. Sorry you are suffering. Did they prescribe a laxative with the Ondansetron/Zofran as tied up bowels are often a problem with that medication? That certainly sounds far worse than any normal , even severe, pregnancy sickness. You'll find plenty of support on here. I include my normal spiel that might help. Most sufferers find that they improve a lot at some point between weeks 14 and 20. Even those who are unlucky enough to suffer throughout generally are not as ill later on as they are in the first part. 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. When reporting on the vomiting to doctors, remember to emphasize the number of heaves in each vomiting session, as doctors tend to count these as 'vomits' and this can lead to their underestimating the severity of your symptoms. Besides drinking through a straw, here are some drinks that have helped others: full sugar flat coke (if you don't find it too acid), 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, Robinson's fruit drinks, Rubicon sparkling mango drink , raspberry Lucozade sport and frozen ice cubes of flat Lucozade sport . Foods of a sort include tinned fruit, cuppa soup, nibbles of crisps and chips, cheap ice cream, Scotch pancakes, bagels and biscuits and slices of melon and mango. Protein drinks have also been mentioned.
abbs1 Great advice as ever for nomeslice and everyone. I am glad that Xonvea has helped a lot,but I am sorry to hear of tonsilitis. How horrible. The swollen throat with that is nauseating without Hyperemesis. Yes, at least it isn't quite so hot.
Thingymaboob and Ttcbn2 Sorry to hear that you are bedbound today. Hoping for better days for you.
Apologies to anyone rudely overlooked.
