I had it bad with my twin pregnancy. So bad that i was on a drip a few times, lived on 3 zofran a day and lost 20 kg during my pg! I vomited from the moment i found out i was pg until the day i delivered- so badly and violently that i burnt my oseophagus and managed to do some dental dammage due to the bile burning my mouth as well.

I was terrified it was going to happen again but i did some research and found a great TCM practictioner who helped heaps. I also vested in a set of sea sick bands which i got a little bit of relief from.

I also waited till my twins were at school before we got pg again so that if it was bad again, then at least the kids were at school.
With my singleton pg i was sick but got away without having any drugs to stop puking and i managed to stay out of hossy. No where as bad as the twins!! TCM made a huge difference and it stopped the really bad puking. M/S eased off at around 14 weeks this time thank goodness and i loved the rest of my pg!
good luck and maybe look into alternative therapies to help out! Worth a go!
