I agree, am on pg 3 with hyperemisis, and if you are this sick so early, I'm afraid it's likely that you have it too. I have tried all the options ; pregnancy 1 - not diagnosed, horrific, pregnancy 2 - had acupuncture, helped with sickness not nausea, pregnancy 3 - ondansetron from 6 weeks. Just couldn't function on any level without them. And still not functioning in any way normally, the headaches and exhaustion are shocking. But, I was absolutely determined to be as well as possible for my children.
My GP wasn't at all helpful re meds, they have about 5 on the list before you get ondansetron, because it's expensive. I called out of hours at the weekend, having already called emergency gynae ward, and got a referral there. They see women with hyperemisis the whole time, and know that ondansetron is the only thing that works for many women.
I wish I'd known to do this with my 1st pregnancy, which is why I'm posting this to you now.
Even if the drugs help, it's still a case of getting through each day, so i would have a contingency plan for your work.
Good luck, you are not alone.
