i also had really bad MS (non stop puking everyday) until my 5th month (21-22 weeks). Went to the hospital to be put on drip as well. Anyway when my MS finally ended, it wasn't a total stop as well.. it slowly and gradually stopped for me during that period.
Nothing worked for me and i tried everything... crackers in the morning, preggie pops, ginger sweets, ginger tea, anti vomit pills etc. So much so i totally skipped having dinner cos i was afraid of vomitting. I rather sleep through dinner time. Lost about 5kg of weight during this period.
Its just something our bodies go through and we need to "tahan" until it stops.
I know its really bad ladies....... theres a light at the end of the tunnel.. just tahan!!!
