mia22221 Welcome. Everyone is very helpful here. I hope the cyclizine continues to help, but if it doesn't, there are other meds that they can try.
On the length that this typically lasts and other things, here is my normal spiel which I hope will help. Here is my usual spiel, which I hope may be helpful.
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 besides that apple juice and foods of a sort. full sugar flat coke, ice lollies, the juice of tinned fruit, Lucozade, apple juice, 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 and Robinson's fruit drinks. Foods of a sort include tinned fruit, cuppa soup, nibbles of crisps and chips, cheap ice cream, Scotch pancakes, slices of melon and mango, grated cheese, baked potatoes, grated cheese and biscuits.
StayClosePooky Congratulations on Lily Dulcie. Enjoy her, as you have had a long haul. Thank you so much for your encouraging message.

justtheonethen I have been wondering how things are with you. I am glad you are so near the end and all luck for the induction. Do tell us how things are when baby is here, as SnowWhite2020 says.
JadeBA2 Constant nausea is dismal. Unfortunately, that can be hard for the meds to relieve. Do you find an anti acid helps? The spittle is horrible. Never worry about tmi, no such thing on here. Some find boiled sweets help with the bad taste, but its so difficult with the excess saliva, and many go about with a spitting bowl or as others say, a towel. It's awful. For many it does reduce later on. On grim side symptoms, I was going to ask if the doctor prescribed a laxative with the Ondansetron as its locking up bowels is such a common side effect?
Waves to Herewegoagain SnowWhite2020 and everyone. I hope the insomnia isn't too bad.
