@jemk83 That's insane - you're sick three times a day IF you stay still, and the doc won't put you on meds? I'm in Canada, so things may be different here (our DD was born in England, so I know pregnancy/birth is much less medicalised, which overall I think is a great thing)...but my midwife was offering me a Diclectin prescription from 6 weeks. I finally caved and went for it around 10 weeks, and at last I'm feeling human again.
I hadn't wanted to go on meds, but the Diclectin is just a combination of B6 vitamin and a tiny amount of the stuff that's in Gravol (which itself is now considered safe in pregnancy). Just had 12 week scan, and all is well with the baby, but I'm still hoping to wean myself off the pills in the next few weeks. Won't be above taking them again if the nausea returns, though - I was getting quite depressed as a result of it, so you have my sympathy!
