We went to Budapest. I found my nausea was a lot better there, and I did have some time when I didn’t actively feel sick (I definitely didn’t feel right, but it was a lot better!). Also, everything there was very cheap, which was helpful. And there was a gluten-free restaurant round the corner from my accommodation, without which I might not have survived! (DH let me steal anything from his plate, and ate anything I couldn’t handle, which was an absolute godsend. He didn’t get many chips.)
Honestly, though, anywhere abroad which is nice is probably helpful. Just been working in Geneva, and found that anti-nausea bands were basically not necessary for the first time in this pregnancy. It was a shame to return home and feel vaguely rough again!
If you feel like it would be good for you to eat fruit, perhaps consider tinned pears - they seem about the least offensive to me (I almost ate a complete real pear one time, but didn’t want to repeat that particular experience!). Also, the juice/syrup water might be easier to drink than a real drink.
Lolly ices can be helpful too. And when you definitely need to eat something, but not any actual food which exists, you might consider half a chicken or vegetable stock cube in a cup of hot water, perhaps with rice noodles if you’re feeling adventurous. It is about as easy a thing to consume as possible, and really helped me at my most desperate.
You need your DH a bit more on board, though. Mine initially thought I was being grumpy, but I was actually just feeling very, very ill. Eventually, he decided he’d better be extra-helpful, and delivered more than one meal to me while I just lay there on the floor in a most pathetic manner (“meal” being a loose definition!).
You should try not to clean your teeth straight after you are sick, though. The acid weakens the enamel, and it needs 20-30 minutes to settle down afterwards, or it gets damaged.
On the subject of teeth, I switched to a children’s toothpaste and mouthwash, and try not to use the adult stuff right now - the milder flavour is much less intolerable. I brushed my teeth top outside, then top inside, then bottom outside, then bottom inside. As soon as the toothpaste flavour started to become intolerable I rinsed, and as soon as brushing my teeth became too much I stopped. This meant that some days I didn’t clean my teeth properly, but it was better than setting off the gagging. The mouthwash helped to keep things healthy, I think. And I used a small, non-electric toothbrush, although some people prefer electric.
The medication might be helpful. I didn’t realise it was an option for me, but in retrospect I’d probably have benefited. Maybe give it a couple of days to see if getting up as soon as you realise it’s time to eat will help you, and see the doctor if it’s not effective. Keep an eye on things as week 9 approaches, too - if things become less manageable, you can re-assess.
Good luck! It’s pretty hellish, but it will pass!
