My son is now 11 years old and I am tentatively considering a second child but it's highly likely I will experience hyperemesis again and the thought fills me with dread. 
Last time around it was a roundabout of stays in the hospital being rehydrated and given non oral anti sickness meds. I'd then be sent home with oral meds and start the cycle all over again. Absolutely horrible and I also experienced a mixed response in terms of medics - some very nice and others actually quite horrid and ignorant.
I'm really hoping that there are maybe more medication options and awareness now???
